A fraud? Took tiny USD to consecutive 11-1 records. Then took Stanford, the Northwestern of the Pac-10, from misery to a 12-1 record, including beating USC in an epic upset and at USC's zenith. Took the Niners to 3 NFC Championship games in a row, and a Super Bowl. I get that Michigan is finding its way under him at a consistent 9-4 and nobody in Ann Arbor is jumping for joy about that. But by the same token he's running a clean ship and he as to compete against OSU, arguably enjoying one of the greatest combinations of coaching hires and recruits in CFB history these last few years. And he certainly hasn't been blessed with much good fortune of late in the random generation of bounces, calls, etc, either.
Go ahead and 'hate' on Harbaugh, but he's no fraud. He's proven to be a very good coach. Not perfect, but not a fraud.
