We definitely don't have that back to basket type big and I've never seen one wear a SJ uniform since I really started seriously following in 2011. Keita has great size but as others have said, not much of a nose for the ball and comes off as pretty soft IMO. He doesn't attack, he seems to avoid contact if possible even with routine layups. The impulse to avoid contact might be negatively affecting his ability to finish. Kind of like when an announcer says a wide receiver "heard footsteps" from a defensive back and they don't concentrate on catching the ball instead. Roberts is very skinny and raw, but I saw him shooting an hour before the game and the kid can at worst be in the same ballpark as Tariq Owens IMO with more time, just a bit shorter. He had a surprising mid range shot that looked smooth but is probably not game ready yet. He plays harder than Keita and he just seems to get a jump on balls that Keita doesn't. Someone give the kid some burgers! By the way, having Mussini this year would have been massive. Not a monster, but he's the typical Butler or Creighton type kid who may not be the most athletic but can rain 3's in bunches.
Regarding refs, not sure if you could hear on TV but there were several pretty loud "These refs suck" chants. It does seem that the refs don't mind sticking it to Mullin from what I've seen vs. other coaches. The tech was very silly on Heron. Who calls that at home? It's like pulling a guy over for doing 56 in a 55. Maybe it's technically illegal, but why pull someone over for that? The missed over the back was terrible too. Simon had a Butler player crashing over his back to get a rebound and we got called instead. It was in the final minutes too. Ponds leaving ball at midcourt was stupid and immature. This will be a major concern of NBA scouts...maturity needs a lot of work IMO but he just has natural talent. Mullin ran out to go get the ball and I believe St. Jean gave Ponds some words of caution not to ever do that again.
