Jim Harbaugh knows how to have his advice stick in a young mind like hot shit flung at a wall made of fly-paper. Make it homoerotic, vulgar, and kind of uncomfortable to listen to. No way anyone at that camp will ever forget what came out of his mouth that day. This video comes from back when Harbaugh was the head coach of the University of San Diego. It's over an hour long but the best advice a young quarterback can ever receive starts just after the 17-minute mark.
