I completely disagree with your comment that the "offensive line can pass protect". They were awful last year (and have been for several years) and it's basically the same group coming back this year. Last year, we'd blitz on defense and still couldn't put pressure on the opponent's QB and all the opponent would have to do is rush three lineman and they'd be hurrying our QB within seconds. Last year, both our offensive and defensive lines were awful. I don't expect them to be much different this year as most of the personnel are the same.
