OK, so this is not likely to be a popular opinion but it is IMO reasonable. I think we are a elite 8 team if we can remain reasonably healthy, so lets get that out of the way first.
Now had Joel were no longer with us, yet again, I think we would be a elite 8 team again with the lack of notable injury qualifier. No slam at Joel but I do think we would be able to cover the PG position with Jalek and 7th, the position is better with Joel on the floor but I think by later season we could be good enough to be a elite 8 team without Joel. Without Theo much the same, feel Cam could step right in as our 3 and be backed up by either BRob or kenny, we are better with Theo but with out him I* still think we could be elite 8 level by season end. We learned to play with out Marcus and Brice.
Now if we had neither of them because I feel by later season we would have solid parts at their spots, I still think we would be elite 8, just a harder seeding to get there, more losses.
If we had Tony, Joel, and Theo honestly, still see us as elite 8 but with a better chance to get to the final 4, just would really depend on how much Tony would have improved over this off season. I assume it would have been a lot as most of our frosh do but I felt he had further to go than most did.
I still think, at the end of the day we go as far as our front court will allow and I do not know that our freshman front court guys are able to give us enough this season to be more than a elite 8 team. But Roy's teams, unless hit extra hard by injury to players he has depended on for that season, has teams that gel together by late season and become very hard outs and I think we would be that even if we didn't have Joel or Theo, glad we do have those guys because I do think we are much better with them but I as well think the kids behind them on the depth chart can play well also with increased PT that would be there if Joel and Theo were not. What kills you is to lose a key player late more so than not having a kid for the whole season, you learn to play without the kid that graduates or leaves early, very hard to lose a kid to injury late season when his back ups have not had the time to play in to their game. IMO of course.
