Every year it seems like people predict that we will go 9-10 deep on the regular rotation, but when it comes down to it, 8 is always the limit for a Beilein team, even his most talented ones. Other guys will play, certainly, but the number who play every game, regardless of how close the game or how tough the opponent, seems to be limited to that. There doesn't seem to be anything new or special about this year's roster to change that.
Right now, I would say that Simmons, Simpson, MAAR, Matthews, Robinson, Wagner and one of Teske/Davis are locks for the the regular rotation. That just leaves the questions of whether there will be an 8th, and who it will be. Barring injury, I'd say that Brooks and Watson are the least likely. Which of the remaining three will depend on how quickly Livers and Poole come along, and which one is shooting the three better. Don't know which I'd prefer at this point.
