Chargers' Harbaugh reveals Bo's bold challenge that catapulted him as Michigan QB

Los Angeles Chargers' head coach Jim Harbaugh has had some incredible influences in his life from his father Jack, a Division 1A college head coach, as well as his older brother, John, the very successful head coach of the Baltimore Ravens.

There is one man, outside of his family, that also influenced Harbaugh greatly, both as a player and a person: The legendary head coach of the Michigan Wolverines -- Bo Schembechler.

Schembechler recruited Harbaugh to Ann Arbor in 1982. He knew the family well as father Jack had been Bo's DB coach from 1973-1979. Young Jim arrived on campus with a lot of confidence (is this a surprise?) and there was talk of him playing much sooner than later. Schembechler was a bit old school and wasn't about to start a true freshman. He was also a keen evaluator of talent and personality so while Harbaugh was hailed as Michigan "passer of the future", he didn't start his sophomore year either.

Going into the 1984 season, the Wolverines were looking for a starting quarterback. It's hard to imagine, looking back at Harbaugh's collegiate and professional career -- as a player and a coach -- that he wasn't going to be the defacto starter. If Schembechler was sold on Cool Jim as his starter, he knew making him work for it was the smartest way to go, both for Harbaugh and the team -- and his method of motivating his young signalcaller was pure Schembechler gold, as Harbaugh related on The Glue Guys Podcast recently.
