Offensive line, without a doubt. If our line could run block better we could potentially have a little more success in the red zone. It'd also help if Henne were more accurate and Marshall actually caught the ball in the endzone for a change. The biggest thing is pass protection. If we could just do an average job of pass protecting we'd be much better off. The O-line destroys drive after drive. Sacks, penalties, interceptions caused by pressure, negative plays are killing drives. It seems on every other possession Colombo or Incognito are single handedly destroying a drive by putting us in 2-16, where we promptly run a draw and a short crossing route to punt on 4th and 8. Ive seen it plenty in 3 games.
