Michael Zordich, the cornerbacks coach at Michigan, was a blue-chip recruit back in the day. Both Michigan and Penn State wanted him, and back in the '80s, both clubs were in the peak of their heyday - a combined 25 ranked seasons in the thirteen years before Zordich's freshman year. Many other programs wanted him as well, but Zordich made up his mind quickly and shut down his recruitment out of loyalty to Joe Paterno.
Michael Zordich has also been an underdog, a scrapper. When he was drafted by the San Diego Chargers in the ninth round, he got cut by the team before his rookie year started.
