MB, while I agree with your data side of it, if you were a Michigan fan that went through a VERY LONG period of losing to the rival and never finishing the job in games that were competitive(which many weren't), the Edwards 75 yarder would have been more meaningful to you. Yes, the odds to win might have shown in the 90's, but that run... was the moment, Michigan faithful that had been through a long stretch, that they were able to feel the "this is happening!" moment.
I get your perspective, but when you're a team that goes through a period of not shutting the door, it makes plays like that even more powerful when the game is technically not over. Stats say one thing.. living through Tressel and Urban told me that game wasn't over and that TD was big.
