Carlton Bragg was 6-8, 220 last season. This year, he's 6-10, 240. He's gone from a Morris twin body type to LL's body type. He's having to learn how to play as a post player instead of a stretch 4. He's also having to do this in a primarily 4-1 line up. In practice, I'm guessing it's almost exclusively 4-1. Bragg to Lucas high-low with Bragg in the high post would work great, but I don't think Self can do much of that in practice because KU doesn't have the bodies in practice to do so. KU literally has 4 healthy big on the roster and by healthy I mean healthy enough to practice and play in games when needed because Coleby is nowhere near 100% from his ACL injury which is why he isn't playing more when he could be a solid role guy for this team if healthy.
It does appear that Bragg's new size has diminished his athleticism which has kept him from doing some of the good things he did last year on offense. Bragg is learning how to play in his new frame and is struggling to make the adjustment to a physical presence because he was always much more of a finesse guy before.
