My top 3:
2002 Washington (I get chills every time I watch the Brabbs kick going in with Beckman on the call)
2003 Notre Dame (This is classic Michigan Replay dialogue between Lloyd and Brandy plus a 38-0 shutout of ND)
2003 Minnesota (It was awesome to see Lloyd celebrating in the Metrodome locker room)
It's mostly the Carr era for me, since I was too young to remember Bo and Mo.
