The only thing I can criticize Callahan for is his inability to have the nads to get rid of his defensive coordinator. Look at the guys he recruited. We could score points. We simply could not stop the other team.
As Lou Holtz once said, "The hardest thing for a head coach to do is to fire his friends." He was, of course, referring to Callahan. It is the only time I have ever agreed with Holtz!
Tell me one thing. At what point was the defense so bad that Cosgrove had to go. It wasnt after 2006. That defense was playing at a championship level second half of 2006. 2007 went haywire. Obviously Callahan wouldve made a change after 2007 if given the chance, but there was no reason to get rid of Cosgrove after 2006, or even after 2005 for that matter after the improvements the team made on both sides of the ball down the stretch of that season.
I'm just trying to be a voice of reason. We all look back and say "derka derpa, fire Cosgrove, la de da", but really, he wasnt that bad until the last season for Callahan.
