Tom Brady may be the greatest quarterback of all time depending on who you ask.

Nobody doubts his greatness. And just about everybody knows that he went to Michigan before he dominated at the professional level.

On Saturday afternoon, hours before the No. 14 Wolverines travel to take on No. 12 Notre Dame, Brady wished his alma mater good luck on Instagram:

The Wolverines and Fighting Irish are slated to meet at 7:30 p.m. at Notre Dame Stadium. The game will be televised on NBC.
