Hearing from a reliable source Jim Harbaugh will tell the team today / tomorrow he is leaving to be the head coach of the Miami Dolphins. Could have taken the Minnesota job. Preferred Miami. ( outside chance Michigan pays over the top and he stays ) but bet on Miami.

Huge news if true. Will have major implications for the B1G balance of power and recruiting for years.
