They didn't stop him on that play or in the game! Despite the "loss" on that play, and going out of the game in the 3rd quarter, Duke still ran for 97 yards on 23 carries!! That's against probably the best defense in college football.
Not having him the second half of the season was a HUGE loss, and it made our offense much more predictable. Louisville's D would not have been able to pin their ears back in that game to the same degree if he were in there.
