For the 2011-12 season, the way I see it for now is we have 4 guys (Lindsey, Harrison, Greene and Stith) to mainly play 2 guard positions.
IMO, at least for now, Garrett, Sampson and Harkless will not see a lot (if any) minutes at the 2 spot. They will get their minutes at the 3/4 along with Pointer and Polee.
If this is the case, I can see Stith getting 15-20 mins a game. At least until Lindsey and/or Greene play that much better than him in games. I don't know why most of you don't see that.
For the 2012-13 season, I see it completly different. Unless one of the guards becomes a one and done, I do see a log jam at the Guard spots and someone isn't going to be happy.
