Michigan coach Jim Harbaugh joins the chain crew while recruiting in California

Jim Harbaugh isn't someone who will sit around when there's work to be done. He's made that abundantly clear to anyone who has ever been around him.

So when he saw that he could join the chain crew at the St. Mary's - El Cerrito contest Saturday in his old Bay Area stomping grounds, he didn't hesitate to get in on the action.

It's been an eventful weekend back in the Bay Area for Harbaugh, who also announced the homecoming queen Friday night at Antioch High, a suburb of Oakland.

If there are any games tomorrow, he might fill in as a referee.
