Andy, I think the exact same speech could be given, with the exact same conviction, to an Ohio State football team. (Edit. - Bo says "Michigan" twice in the last few seconds of the clip. Without that, it could be delivered word-for-word in Columbus.)
I don't know how many former OSU players who also played in the NFL you've spoken to, Andy; I know several such players out of Michigan. And to a man, they say that they never had so much fun as when they played football in Ann Arbor. Not in high school (where they were basically all H.S. all-stars and all-state selections); and not in the NFL, or MLB. The NFL, they all say, was just work. And often times extremely unpleasant. Nothing, for them, came close to the experience of college football.
My guess is that there is a lot of the same feeling in Columbus. I think players coming out of Oklahoma think the same way. And USC; and probably Notre Dame and perhaps a whole lot of places. I know it is true for Michigan. Bo had it right, and it has always been interesting to hear somebody verbalize it. I can actually picture Woody Hayes giving the same speech, and I'd have liked to have heard it, because coming from Woody it would be damn good.
