better athletes. In the red zone, with less space, a more talented (athletes) defense is just not going to let you execute your vanilla plays very often. Remember Taysom's 2 failed 2 point tries against Utah and BSU? Offensive line failed. I'd like to have a few plays that aren't contingent on 6-9 players (linemen, receivers, Rbs) all winning their matchups.
Boise State has been great at it. It led to wins which led to better athletes.
