As well as our secondary/pass defense has played this season, all season long we have been poor at point of first contact tackling. We've won games in spite of that. It did us in vs. Tulane, where even with the pick 6 & kick return, we still possibly win that game if we can put their QB on the ground when we had him in the backfield.
Marshall's QB took every advantage of us not being able to get him on the ground at initial point of attack and contact.
