It depends on the Lettermans attitude. Is he willing to except whatever role that he falls into? Or is he going to be a cancer because he feels that he should be starting or etc. If he can not be a team player then you cut him before he can infect other players with his negative attitude. If he is willing to except his role whatever that might be then he will probaly be a great asset to the team. I have talked individually with guys in this situation in the past and have asked them point blank. Some guys have decided to walk away and some have stayed on and helped the team anyway they can. Some have told me that they would do whatever they can to help the team and after a few games started to complain to other guys on the bench about playing time. Then you to deal with it during the season. Its a tough call but one that has to be made.
