Notre Dame defense has to solidify in second half

Darius Walker (125 yards) is running through the LSU defense at will. The problem for Notre Dame is the Irish defense can’t stop LSU, therefore Walker cant not be used heavily just yet. It appears the Irish are going to have to outscore LSU and that doesn’t play into the hands of the running game.
That being said, if the Irish defense can somehow make some adjustments to stymie JaMarcus Russell, this game could get interesting.
