Along with his offensive acumen, he did a very good job of changing the attitude amongst his IU players. In return for their loyalty to him, he’s tweeted about those who did stay, lauded those guys upon their graduations long after he was gone from IU and the guys he coached here who went onto the NFL. The guys who played offense for him at OU and NU also seem very loyal to him.
Just wish he would have found some semblance of balance when it came to the defensive side of the ball. And gotten his off the field demons in check.
