I think that what he has is where he is basically out of cartilage and is rubbing bone on bone... While painful, he can play with maintenance. NFL players play for years with this. If he can give us 15 minutes a game I think that would be great. Regarding depth I actually think we will be fine.
Cook, Bartley, Lloyd, Fletcher, Pippen, Bol, McGill (who I love), Gooch, Rudy (If needed, can be serviceable, like against Mo. St in the valley tourney)
Now if we end up with Rudy as the strict back up I think we have problems, I would be temped to let the sissoko suit up and play.
Regardless of Bol I think we could cause big problems for teams with a line up of Cook, McGill, Bartley, Lloyd, Fletcher.
It'd be cool to see Thik stay on the floor and play above the rim this season. It would definitely help solidify Southern at the defensive end of the floor.
