It was indeed a listless Michigan performance. When Indiana scored the tying TD in the end zone just below us, the whole place just went flat. My roommate and I had snuck in a 12-pack of Stroh's (you could do things like that back then), and I began gathering the empties strewn at our feet and stuffing them back into the 12-pack so we could at least get our $1.20 deposit.
I remember looking up and seeing the ball in the air, but headed for the opposite end zone. I was filled with disgust (tied by INDIANA!) and Stroh's and no desire to witness further futility. Then the place exploded. I didn't see it until Michigan Replay the next morning.
