Polian is too emotional?

Greg Gabriel at the National Football Post makes some fine claim chowder. Yesterday he stated the case that Bill Polian simply thought too highly of Curtis Painter, hence the QB situation:

Why would the Colts pass on drafting a developmental quarterback? Well, their thinking at the time of the draft had to be that Manning was fine and they had a quality backup in Painter. The problem many clubs have is they overvalue their own players. They think what they have is better than what they can get in either the draft or free agency. Too often that’s not the case and it comes back to haunt you. I have always thought that clubs should have an outsider who is not emotionally involved with the club to evaluate its players. This way you can get a fair and unbiased opinion.
