Polian is probably one of the only big names that will come here. Sure the Colts had a 2-14 season, but it put them in the position to draft Andrew Luck and they control their destiny to make the playoffs this year. What fresh blood is going to want to come here? Russ Grimm and Ron Rivera refused the opportunity to interview for the HC position in 2010. Not to mention the rumor that Harbaugh said no as well. Polian is older, but he has built winners everywhere he went.
From a marketing standpoint it might generate interest in season ticket sales next year.
I agree with you about his head coaching decisions, they have been suspect at times. I still believe that Marv Levy was an average coach with outstanding football players. That being said any change will do.
