In the wake of Campbell's ousting, former Michigan quarterback J.J. McCarthy sent a heartfelt message to his former U-M position coach via social media on Friday. "Wouldn't be where I am without this man," McCarthy wrote. "Changed my career, as well as my life. Keep being you, Coach Kirk Campbell."

Embattled play-caller Kirk Campbell is gone. The nation's top QB, Bryce Underwood, is on board. The future of Michigan football looks brighter.

Michigan fired offensive coordinator Kirk Campbell on Tuesday after a 7-5 season that saw the Wolverines slip to No. 128 in the FBS in total offense and No. 130 in passing offense.
