When Michigan defensive end Aidan Hutchinson saw that new Ohio State co-defensive coordinator Greg Mattison called Michigan "the team up north," Hutchinson took it personal.
The sophomore defensive end tweeted a snake emoji implying his former defensive line coach had betrayed him and the Wolverines defense.
Hutchinson explained his emotions on Saturday after Michigan's spring game, saying Mattison meant a lot to him and packing up to coach with Michigan's rival was something he couldn't stomach.
"Coach Matty, you know, he taught me so much when I got here, and I'm not taking any of that away from him," Hutchinson said.
