Funny that you mention that Colorado game.
That happened prior to my Michigan fandom. In fact, at that point in my life, I rooted for anyone and everyone that played against my father's favorite teams.
I don't know why, but I did.
I can remember that day like it was yesterday, even though I had just turned 8 years old. I remember him being back in his bedroom. He had fallen asleep with the game on, assuming that it was over. I was out in the living room, watching, ticked off that Michigan was about to win.
Then the ball went in the air, and that Colorado player came down with the ball.
I sprinted straight to my dad's bedroom, jumped on the bed and started screaming. He had no idea what was going on. Finally I belted out "Michigan lost! Michigan lost! hahaha"
He couldn't believe it. He ran back out to the living room to see the replays.
He, obviously, wasn't very happy.
Anyway...just thought I'd share that story since that game was brought up.
My first true season as a fan, watching every game, watching all the Michigan Replays and so forth, was....1997. Pretty good time to start.
