It’s perfectly possible to play 9 guys a material role.
Yeah, slice it up however you want.160 minutes divided 7 ways in the 1-4 spots. ~23 minutes each. A couple will inevitably only get 10-15, rest will get 25-30 on any given night depending on match ups/fouls/performance. And of course things are likely to tighten up and slant towards the best guys down the stretch.
Main limitation, if you could even call it that, is we are unlikely to see anyone besides probably AK average 32 minutes like they possibly could on a thinner team. But ask Mahaney if he'd rather play 33 minutes a game for a team that lost in the first round or 28 minutes on a title winner and it's easy to understand that it isn't difficult to get guys to buy into a 9 man rotation when you keep winning.
Only guy I feel for in this situation a little bit is Ross because I doubt he cracks the rotation in a meaningful way with AK back. I hope he can carve out a Stewart type role down the stretch and be primed to play real minutes as a junior though. Singare I think had to expect to not play much this year either, and Abraham as a freshman probably understands he's going to have to wait his turn. Would love if any of them were willing to redshirt, but that doesn't seem like it ever happens in college hoops.
