Bert Bielema joked about attending Michigan's open practice at IMG Academy on Friday. Mark Dantonio and Butch Jones joked they'd like to join him.
The NCAA said it would be a violation for other coaches to attend, but that didn't stop Jim Harbaugh from firing a single shot at Tennessee's 21-17 coach who's currently dealing with a Title IX lawsuit:
Suggestion to my Rocky Top colleague, rather than lunch in Florida you might spend your time and focus attending to your present team.

That's a confirmed knockout.
