My college coaching career included stints at a future PAC10 school, in the Big Ten, and in the Big 8. I won a national championship with a legendary quarterback. I won 70% of my bowl games. One of my former assistants greatly influenced where a future NFL Hall-of-Famer would spend his pro career.
During an blowout victory in the late '60s against my team's most hated rival, the opposing coach flashed me the peace sign, apparently in hopes I'd call off the dogs. In response, I returned half of it. (Now that's a rivalry!)
And a play during a game I coached against Michigan resulted in a rule change the next year that is still in place.
Who am I?
