Grant and Smith were, at best, journeymen level DE's last year. Generated very little pass rush. Our DT's were marginal against the run and generated no inside push at all against the pass.
I don't think that is a fair assessment, especially since our defense was 13th in both rush yards per game and yards per rush, all with a poor linebacking corps. I think our DEs weren't allowed to full out rush most of the time because our D line was responsible for containing the run and protecting our LBs.
