It does stink that Gittens didn't finish at Weber. Good kid, fun player. I'm not sure it was all coaches on that one, because he may not have started as a senior and may not have liked his career to end that way, so I wouldn't begrudge him leaving if that were the case (speculating, of course).
I don't like to pile on college players, but statistically, Cannon regressed last year and there's a reason his playing time disappeared (and is a walk-on somewhere else, not a scholarship player). He had key moments as a frosh but it just wasn't there last year. I'll eat crow if I have to on this, but Ricky Nelson and Trevon Ary-Turner should upgrade from Cannon instantaneously.
I'd be really, really surprised if 4 or 5 freshmen play this year (health aside, of course). If you get any kind of progress from Jordan Dallas, you probably don't see Vialen. You see 1 or both of Nelson/Ary-Turner, plus Kozak in short stints. With Richardson and Baker (plus Chapman as a stretch-4 unlike what Weber has had for a long time), Court would just logjam the guards/wings if you still want plenty of PT for Jerrick Harding (which you do). I'd guess 3 of 5 freshmen see playing time, with Court and Vialen standing to benefit from redshirts the most, in my eyes.
