LJ is going to be 15 pounds heavier and should see the field even better than he did before. And Bohanon is a mediocre passer but an elite runner. The combination of those two things and a coherent blocking effort will do wonders for the offense as it will put pressure on other teams LBs and safeties.
Also our WRs were better than you give them credit for. We sustained big injuries at that position and still torched Cincy and Kansas through the air. And that was without a good run game to give us easy play action opportunities-
