Michigan/Bowling Green connection via Harbaugh, Loeffler and Ay Ziggy Zoomba

I'd heard this week on WTKA that Jack Harbaugh had a Bowling Green connection, but didn't know that he both played and coached there. Anyway, this article talks about Jim Harbaugh spending part of his childhood in Bowling Green learning their "Ay Ziggy Zoomba" fight song (I googled it and it's not bad), Jack supposedly cheering for alma mater today and Scot Loeffler's time in Ann Arbor as a player and coach. Not sure I can remember a game where both coaches had such a strong connection to the opposing team.
