Part of the issue I have with Willie is that he's not the player I thought he'd be. In some ways that's bad and in some ways that's good.
What I envisioned was an ideal front court partner for DeMarcus Cousins. The long 7 footer with unbelievable footspeed and lateral quickness who would shore up the pick and roll weakness that Boogie creates, add weakside rim protection, defend stretch fours and offensively get his points in transition, off dump offs and on 15-18 foot open jumpers when Boogie was double teamed.
Part of it was being a rookie, but Cauley-Stein hasn't been good against stretch fours. He's also not been the P&R destroyer I'd hoped for. Part of this is the habit (which he's improved but still struggles with) of extending the ball handler too far out and then thinking he's quick enough to get back to the roll or pop man. In college he was. In the NBA too often he isn't.
I knew his rebounding would be an issue. I talked myself into believing it wasn't as bad as the analytics showed at Kentucky because (a) he was playing alongside other bigs that gobbled up boards and (b) he was often switched onto a perimter player, pulling him from the hoop. Both are true, but it's also true that he's not a naturally aggressive or instinctual rebounder.
On the other hand, he's shown a fluidity and potential on offense that I didn't know he had. That crossover into a spin move against Jokic had me just shaking my head. His form on his jumper is looking better and hopefully gets consistent but it's just his aggressiveness at times on offense since the Cousins trade that surprises me.
I never thought WCS had star potential. I thought he could be an elite level defender like DeAndre Jordan but he's got a long way to go for that to be a possibility. His rebounding is still anemic and he often appears to shy away from contact. On the other hand, he's had some games where you wonder if he might be as good (or possibly better?) on the offensive end than the defensive end.
Who knows at this point? Lots of young guys are a bit of mystery box but rarely a guy who played three years of NCAA ball at a major university and who is in his second year of the NBA, but Willie's role in the NBA still hasn't been carved out. If he puts it all together he could be incredibly valuable. If he continues to be inconsistent he could find himself as a career reserve or worse.
Hell, this season he was out of the rotation and starting to look like a bust after a season in which I felt it was Karl that was holding him back. Right now he seems to be arrow up, and for the time being that's enough.
