5 full years of Andrea makes it hard to see where a decision could be seen as hasty.
Colangelo stated the obvious. Surely he's never going to convince anybody that Bargnani
proved himself as a capable defender. At the same time he made excuses as to why that has been the case thus far, and sold Andrea's positive attributes. It's really hard to see where Bryan hurt Andrea's reputation at all. Messina seemed to take it far too personally and looks eager to not hold the guy accountable while blowing his own horn concerning what he was able to get out of Andrea.
The fact that an obvious and fair criticism becomes such an issue signals just how much of a problem this guy represents to this team.
