I agree with earning minutes. Showing you belong and earning the starters spot, but still being one among 3 similar players still affords you less opportunity (minutes) then being a clear option at another top level place and then being able to compete head up against those type players in real game action nightly.
I just don't see it as being "scared" of competition as many seem to throw out there when bringing in multiple guys at the same position or having multiple guys at the position back is mentioned as a negative for a player when choosing among his suitors.
Understand, I am not in any way meaning to suggest Pierce picking Michigan would mean he is scared to compete for PT with us, I was talking in broad general terms.
Very true that a big time kid has to look at the quality of depth at his position, a quality back up reduces the need for a coach to have a guy on the floor for huge minutes and the better the back up usually the more time that back up gets, means lesser PT for that big timer.
Specific to Pierce, have heard nothing about him demanding to be a starter but I do think he wanted a clear feeling for how many minutes he could reasonably expect and how he would be used (at the 3 exclusive, at the 4 exclusive, split minutes between the 3 & 4), all very reasonable concerns that he should want clarity on.
