if you can put together a quality a+ d2 program, you can jump right into the BCS conferences. at least, that used to be the case, im pretty sure it still is. you jump around so much, might want to consider sitting tight there and trying to do the d2 -> bcs route! but generally speaking its quicker through low d1 - if you can make it through low d1, that is, definitely not a guarantee into today's game.
