Star basketball players are often obvious from the get: you have your Victor Wembanyama‘s, your Anthony Davis‘s, even Nikola Jokic‘s, if you’re looking in the right direction.
But it’s far from exclusively the case. In contrast, players like Steve Nash, Giannis Antetokounmpo, Kevin Durant, Russell Westbrook, Devin Booker, Jimmy Butler, Jaylen Brown, Pascal Siakam, Kobe Bryant, Draymond Green…I could go on…were all negative basketball players on an NBA court their rookie season (per DARKO).
I watched prospect tape for every name on that list, in addition to some other steep development arc players, to try to ascertain commonalities. But, importantly, the roads are complex, winding and opaque. This is not a comprehensive articulation on what makes players improve.
This is a piece on Cason Wallace. Wallace was indeed a negative basketball player as a rookie NBA player, but not dramatically so. His -0.3 rating on DARKO’s all-in-one indicator is similar to that of other developmental stories Kyle Lowry, Jalen Brunson or Shai Gilgeous-Alexander as rookies. But does he have the same kind of potential to improve?
That’s what we hope to answer. This article will go through five steep development curve characteristics I discovered during my historical improvers tape watch to see how he scores. Through that lens we can better benchmark Wallace’s room to improve, and learn about the nature of development as we go.
Trait #1: Willingness to Initiate Physicality
Cason Wallace’s physicality is inconsistent but overall a positive. On the defensive end, there is no question that Wallace is accepting of physicality. The play above is a prime example, as Wallace can eat up drives into his body with perfect positioning. This is valuable as there is little risk of Wallace bailing out of a play, in fact entrenching himself as he blocks a path.
Physicality is a sign of potential development due to basketball being a physical sport; it’s not much more complicated than that. But more specifically, physicality allows you to execute plays to their fullest extent. What good is effort if, at the critical moment, the player decides to play it safe?
That is the question we face with Cason Wallace’s offense. Wallace, despite all his strength and physicality on the defensive end, is highly prone to settling away from the rim for any semi-closed path. When he has a clear runway, Wallace can look downright imposing attacking the rim:
While Wallace’s off-the-dribble non-rim two rate (pull-up twos and floaters divided by total 2PA) is almost exactly league average, you still get the sense he is leaving money on the table given his strength and driving ability. The flashes make you wonder why his free throw rate was only 0.22 at Kentucky or a miniscule 0.08 his rookie season. The latter was within the twenty lowest free throw rates in the league, a concerning sign.
Wallace’s proclivity for floaters is a vicious cycle: due to stopping his drives short, he loses the opportunity to develop rim finishing craft; because he lacks finishing craft, he has to settle for more floaters.
Wallace gets a resounding half of a check mark for the physicality question, and there are three reasons for optimism. One is Cason’s overall sense of technique, which we’ll get to later in this piece. The second is role, as Wallace was used as a wheel greaser in a lot of ways, but rarely schemed to attack the tin aggressively. That could change as of game one this coming season, with a paint pressure gap left in Josh Giddey‘s absence. Third, which combines with the other two, is how Wallace is very good at taking what’s given to him. Perhaps with more confidence in his body (he reportedly put on 15 pounds this offseason) the offensive physicality will catch up with the defense.
Trait #2: Motor
Watching the greatest development curve players in succession alerted me to one blindingly clear fact: to improve a lot, you have to play hard. This both sounds obvious and like an old school, pre-analytics scout. But it’s a characteristic I may have been underappreciating, no less. Having a low motor does not preclude improvement, nor does having a high motor guarantee it. But to develop from a role player to a star it is basically impossible to not play a little like a maniac.
While it is not surprising that a high motor would show up on tape, the consistency was surprising. Even Devin Booker, not widely considered a high motor player, proved to be a defensive pest as a prospect. Wallace is somewhere in between the high motor players like Booker, Durant and Shai Gilgeous-Alexander and the All-Time motor players like Russell Westbrook and Kyle Lowry, and likely closer to the latter.
Motor is the cousin of physicality: it not just permits play execution, but creates plays out of thin air. Cason has no business having an effect on the play above, one of the few in the league who could get this steal. Below he shows consistency of focus (and indeed, physicality) to track the ball down and secure it.
Motor contributes to development by giving a player more bites at the apple. The higher the motor the more likely you’ll be found in transition or cutting to the basket, or relocating for a three. For a player low in usage, finding these opportunities is essential. As is having the drive to finish the play.
Even though it ends in a made basket, I love the activity from Wallace in the clip below. Motor here means boxing out, nearly stripping the ball and closing out over ~25 feet in an instant.
One more example of physicality meeting motor: the below box out on Adem Bona.
Motor equals opportunity, and Wallace makes sure he takes all he can get. Likely stuck in a low usage role given the Thunder’s higher profile options, Wallace needs to maximize his motor in the share he does get. I have little doubt he will do so.
Trait #3: Small Space Coordination
The above clip, in combination with a few others, are as compelling signs of Wallace’s star upside as you can find. At this point, it is fairly clear Wallace has defensive upside, even just tying together the points on physicality and motor above. But offense is where you can really strike gold, as the impact of the best offensive players exceeds the impact of the best defenders. The ball travels faster than you can move, and can also fly higher than you can reach (with a Wemby-sized caveat). But you need to put yourself in position to have that impact with the ball, and that’s how we arrive at small space coordination.
Basketball is a high-movement sport: according to NBA.com, the typical player ran ~150 feet per 24 seconds on offense, ~130 feet on defense this past playoffs. In fact, Wallace ran 10% faster than the average player on defense while about average speed on offense. All of this movement volume only emphasizes the importance of movement quality. Cason Wallace has plenty of the former, what about the latter?
On offense, small space coordination not only means being nimble enough to create an initial advantage, but, arguably more important, the ability to dance through traffic. We return to a similar concept as the previous sections – the ability to finish a play. Wallace is, decidedly, a question mark on this front.
There are plays like the above where Wallace is able to create a unique footwork cadence in combination with sleek ballhandling. Or even the below from his AAU days:
But those moments are far from consistent. At Kentucky he had 60 drives, comparing favorably to fellow rim-shy Kentucky Wildcat Reed Sheppard at only 49, but far below Rob Dillingham at 93. Watching the tape, Wallace is often able to get that first step with pretty good burst, but never plays around in the midrange. He is either kicking out safely after an initial probe, conceding for a pull-up/floater or, far less common, throwing his body into the rim protector. More small space coordination would mean more complex playmaking, such as biding time handling a pick and roll, dribbling to the soft zones of the defense to draw help, or foul-grifting by dragging your man along with you.
Wallace may have access to moments of small space coordination, but the lack of applied coordination means less practice hitting those spots. Reps are essential to getting one’s footing, literally. Will the Thunder allow him to initiate these dances? Time will tell.
Trait #4: On-Ball Experimentation
These concepts continue to go hand-in-hand, as small space coordination would dramatically expand one’s on-ball opportunities. Wallace’s shy nature in attacking once again holds him back, but not without flashes here as well.
Wallace’s primary way of experimenting is with his pull-up, but even here there is little by way of complexity. Rather, where the flashes are most promising are with his passing.
Beautiful, effective, and more proof that Wallace has access to small space coordination. Wallace uses the screen and then eats up the middle space between his man and the big. He does this with a left hand in-and-out into an accelerated cross to then reset backwards and sling a one-handed pass to the corner. The play is only possible through Wallace’s unusual movement pattern over the two second period.
The value of on-ball experimentation is clear: trying more things allows you to do more things. We’re returning to the importance of creating one’s own opportunity. Experimentation is not Wallace’s favorite way of going about things. His whole thing is reliability, with an assist-to-turnover ratio of 2.0 with Kentucky and 2.6 with Oklahoma City, which shows up in a heavy preference for making the simple read. Most of the time he’s on the court with the Thunder, Wallace is doing mundane tasks.
But Wallace is still capable of deception here and there. In particular, he is able to manipulate by passing against momentum, drawing in help with his eyes and accelerating into gaps.
This is not the most interesting way to experiment with the ball, but it still may be effective. The important thing is that Wallace has options. If the runners and pull-ups drop at a more efficient clip (as I expect…Wallace’s touch is very good), Wallace will have larger margins in which to operate, and maybe the pull to experiment becomes stronger. But right now, partly by scheme but partly by preference, Wallace conducts himself like he wants to remain a role player. An elevated one at that, as Wallace comes off as a perfectionist, but perhaps not significantly adding to the star equity like our huge development leap stories.
Trait #5: Technique
We saved the best for last. Technique is only this low on the list due to how long it took to click for me that’s what I was seeing. In particular, watching the tape of Steve Nash made me keen to this issue. Could it be? Have I really been underrating the most basic, fundamental aspects of basketball? I think so.
The tape of freshman Steve Nash shows crumbs if not large bites of all the elements listed above, but most of all it shows technique.
If you’re sorting through highlights or exclusively watching Synergy clips, you might miss it. Nash’s triple threat is as sound as any I’ve seen, ripping through menacingly while constantly changing his elbow posture to keep dribble, pass and shoot all as options at once. He sets shoulder-wide screens and can take the contact (physicality). He runs routes with intention. When he makes his move, it is decisive and with little wasted motion.
Here is where Cason shines.
As you can see from the above clips, there are a few areas where Wallace shines from a technique standpoint. First, his spot up technique is very strong. While he prefers to one-two into looks off the catch he is also able to load quickly from a stationary position. Wallace was in the 90th percentile as a spot up shooter as a rookie, shooting a blistering 43% on catch and shoot threes. But he’s capable of attacking closeouts relying on technique, too. His pumps are exaggerated in a good way, and he takes a long initial stride, swinging the ball in front of him.
Wallace’s technique is also strong from a physicality point of view. He sets sharp screens, extremely valuable in the OKC offense as he often began a possession with a screen for SGA near the logo.
The technique jumps off the screen on defense. Wallace is particularly adept at mirroring ballhandlers, enabled by a discipline to rely on footwork to block off any path in an instant.
Watch Cason Wallace and you’re watching someone who pays attention to the little things in the lab. He concerns himself with the details many young players gloss over, which speaks volumes to his ability to improve.
Technique is, perhaps most of any of these traits, an indication of latent value. A technically sound player is able to apply that technique to any basketball action, assuming tied to a minimum level of athleticism. Technique is the bedrock of basketball success, and Wallace will only further refine his methods with time.
Conclusion
Cason Wallace is a boring watch for a potential star, but only if you don’t know where to look. Even where he does not completely check the box for a developmental trait, there are flashes. The key will be where Wallace’s on-ball usage settles, where he needs reps the most to realize the most upside. Perhaps there is a plan there involving bench units.
Wallace will undeniably become a star defender. In defensive DARKO Plus-Minus, he is ahead of the curve compared to Jrue, White, Smart and Caruso.
Grading out excellently in advanced metrics as a rookie is a great reason to believe in this story, but it is also embedded in the details. Wallace employs technique with physicality to dodge through screens (already an area where we’ve seen improvement) or to cover the right zone in a scramble.
The offense is the question mark. Wallace is likely a slightly negative to neutral offensive player in 2024-25, but the degree of involvement will tell us a lot. Wallace’s strength is again technique, which enables him to play on or off ball, as a screener or screen-recipient. Should he use the technique to buffer his small space coordination, problem-solving in a different way, Wallace’s offensive upside could be quite high.
I wrote this about Cason Wallace ahead of the 2023 draft:
“…you can become a star through the lack of mistakes as well. Cason has that path. It’s not common to reach it through simply doing every little thing on the court you’ve asked well without a truly dominant area, but maybe that’s exactly where Cason Wallace’s dominance lies.“
One year later, I only believe this more to be the case.
