I don’t recall a controversy over the ‘90 game, but there was a big rhubarb during the ‘79 game as to whether or not Michigan forced USC tailback Charles White to fumble on the one-yard line as he was going in for a touchdown. USC was awarded the touchdown and went on to win the game. That was the fourth game I attended in person.
I think that play started the “ball flys over the goal markers” and it’s a td even if the player lands out of bounds.
That doesn’t work on pass plays-—gotta have at least one foot in bounds in the end zone while in possession of the ball. They oughta make the running scorer have at least one foot in bounds ,over the goal line, with the ball in their possession.
I remember a play where Michigan faked the punt and the UM RB who’s name escapes me - LeRoy Hoard? - ran for the first down but it was called back for a hold. It was not a scoring playing but would have kept the Michigan drive going and extended the game... And Schembechler was mighty pi**ed after the game... at the refs.
