I agree with the commenter who said we won't have a 13-player rotation which almost ended up as a disaster last year. We only started winning games after we tightened the rotation.
My (not so ) bold prediction: Cline is going to redshirt. I know some of you are excited about him but he's behind Mathias and Stephens and is a specialist like the other two.
These players will get 30+ minutes: Hammons, Davis. Swanigan potentially will too, based on how quickly he adapts to the college game. Haas will probably average about 10 min. Unfortunate for him since he has talent but he's behind Hammons and can't play the 4. Now, if Hammons starts out slow (and I would actually bet he will because it happened pretty much every year) expect Haas to get 15-20 minutes again in the OOC part of the schedule.
PG is anyone's guess since we don't have a proven commodity and frankly not much talent at the position. I'd imagine the best defender out of the bunch (prob Hill) will play about 25 min/game and the best scorer will play 15 min/game. I wouldn't be surprised if Weatherford takes the backup spot from PJ.
Between Stephens and Mathias, there will be competition and one of them needs to step it up from what they did last year. They both had their moments but not enough of them. If neither one does, expect Painter to slide Davis to 2, and play Edwards at 3. Between Hammons, Edwards, and Swanigan, we should have three options on offense and won't be needing Stephens'/Mathias' specialist features unless they bring more to the table.
I expect Smotherman to fill his "Marcus Green" role with diminishing minutes. Taylor is the odd man out. I think it's funny how there were so many "We don't need Swanigan, we have Taylor!" posts just a few weeks ago and now people are giving him 5 minutes a game.
