It’s difficult to tell because Johnson was slightly ahead of Stratton, but he had to reach back for the ball because the pass was behind him. I’m fairly certain it’s the trajectory of the ball and not the location of the receiver that determines whether it’s a lateral or a forward pass.
Obviously it doesn’t matter in terms of the outcome of the game. It just would have been nice to add the 72 yards to his rushing total and one more TD to his record. Especially if this ends up being his last game as a Hawkeye.
I’m looking at the ball. The camera angle is pretty good. I would say Stratton let go of the ball about six inches past the 20, and touches Johnson’s hands about a foot beyond the 20.
