Keselowski joins Tom Brady, Derek Jeter at Michigan's 'Signing of the Stars'

The stars came out for the University of Michigan's National Signing Day extravaganza.

Team Penske's Brad Keselowski -- a noted fan of the Wolverines -- was among those invited to UM's "Signing of the Stars" event at Hill Auditorium.

Others in attendance included former Michigan quarterback Tom Brady, retired New York Yankees shortstop Derek Jeter and legendary wrestler Ric Flair.

It was a pretty good day for Michigan, as the team landed the nation's No. 1 overall recruit in DL Rashan Gary.

The event also raised money for a great cause.
