Mine is our receivers hanging onto the football. What they did against E. Mich was nice. Lets see them get open and secure the football against a real team. If they do so, I think we win the game. We cannot play fast and have receivers dropping the football. That sucks the life out of the O and forces the D to defend extra. I think if our receivers can make plays but most importantly secure the football we win. Curious to hear what others biggest concerns are?
