it's not true at the same level. start with the SEC alone (to your credit, you brought up two SEC examples - though that's where the apples to apples comparison ends) - it has the best teams and best athletes. and while spacing in general is bad in college, it is worse on a team like texas that relied so heavily on the guy in question. 20 ppg and the next highest scorer was at 12 ppg.
fears averaged 17 ppg and he had a teammate that averaged 16 ppg. defenses couldn't just key on him the way texas opponents had to with Tre. also, getting into the paint is Fears calling card - he shot 28% from three - if he doesn't beat people off the bounce we're not even talking about him right now - it's his greatest strength. apples and oranges. nobody is saying Tre is elite at beating people and getting to the rim, rather i'm offering reasons why some might be able to reconcile the idea that he has a good first step, but had trouble getting by people and into the lane.
CMB is a 3/4 who weights 250 lbs, yeah, his rim attempts are going to look different than that of a shooter. bottom line, in your answers, we're seeing you don't really want to reconcile those two things - you are looking for reasons and examples why it CAN'T be reconciled rather than accepting reasons why it perhaps can be. you brought up a fellow SEC guard whose calling card his ability to get in the lane and a 250 lb bruiser - and that's fine. i've given you reasons it can be reconciled - you don't have to agree but those reasons are there.
bottom line is that while all these guys are college basketball players, each situation, each team, each offense, each player, is unique. nuance matters. but if you don't want to see it, you won't. and i can't help you.
