Not really. He had huge coaching blunders with the way he coached Skal in trying to turn him into a low post guy, Murray in trying to make him a driver when he's a shooter, and Willis by not giving him a chance until late.
Bad, bad take.
He's had example after example of long, lanky centers (some with absolutely no muscle at all) who came in initially getting shoved around in the post by more mature guys, yet ended their careers as fearsome beasts near the basket - AD, Noel, Willie, Karl, even going back to Camby - for all of them, he was able to toughen them up by developing their post repertoire and by letting them go head-on with the big boys in the paint.
So for one kid, it doesn't work because Cal can't extract that level of toughness from him, and because Cal gave it a shot until January before abandoning that historically successful model, he's making some huge blunder? Cal said he screwed the kid up to take all the pressure off of Skal - but the reality is, if you've had a million kids who fit the same physical profile who developed post moves and all turned out to be top 6 picks in the draft, why would you abandon ship after 5 games with the new one? It doesn't make any sense.
Murray should be driving as well as shooting. He can be elite at both. Cal is not trying to make him "not a shooter". He's telling Jamal to stop taking ridiculous circus shots, which he has done since his high school days.
Willis was not doing what he wanted in practice. Just like Jorts or Miller, he has absolutely blossomed when he finally started giving Cal the consistent effort he demanded, on defense as much as offense, and in practice as much as in game.
The Willis fans always complain about favoritism when Cal gives Skal any minutes at all because he's soft - what about playing a kid who doesn't do what you want in practice when other kids are at least trying? Derek even
admitted that he wasn't putting in as much effort as he should have, for crying out loud? That sets an awful precedent if you let that kid play.
Now, he's putting in the work, and he's been rewarded handsomely.
