Good luck to Hurley with this one. Vital has received little guidance on the above to date, plus he thinks he's a far better player than he actually is. That's could be a tough combination to overcome.
I honestly think that you're underestimating CV's mental fortitude.
CV has "it."
All guys who max out their potential, or come close to it, have it. It's what Donyell and Rudy and Andre and Stanley didn't have quite enough of. Shabazz had it. Kemba had it. Rashad had it.
It's the belief that "I'm the man, and I can make it happen when I need to."
Can you imagine Stanley with CV's brain? My G-d, that would be an NBA all start talent right there.
But let's not confuse having "it" with being uncoachable or unwilling to change. Quite on the contrary - CV is all heart, not some chucker seeking glory (think SCIII). The guy plays super hard on both sides of the ball. Chuckers and glory hoors don't play tough D, because there aren't any easily consumable stats to be had.
CV's competitive spirit is such that he's going to do what it takes to get on the court and stay on the court. Mark it down. CV is going to do GREAT under Hurley. Bookmark this and call me a fool in January.
Don't conflate him running a bit wild under a rudderless KO system to some sort of intrinsic flaw - can't blame a man for wandering when he has no map.
