Sort of. Campbell hit Clifford and then PSU kicked the FG to go 17-3. Then Iowa took the ball on the next drive and scored. Technically, it was 17-3 when he got hurt, but it was definitively 17-10 before Roberson had any impact on the game.
There can be no doubt that the injury substantially changed the course of this game. I will not, and would never, argue that point.….but because he went out when he did, we’ll never know if Phil Parker would have found an adjustment to slow what had been a solid PSU passing attack.
But the score was 17-10 when Roberson first went into the game.
