PFF has Rousseau as a top 10 DE. He is the highest graded DE run defender, but only in the top 40 for pass rush. Players ranked above him in the top 10 are pretty much the household DE names, Garret, Parsons, Hutchinson, Anderson, Verse. Bosa is ranked 15. DE's are not our problem, its the injuries in the interior DL and McD's affinity for oft injured undersized LB's who aren't great tacklers. Couple that with the falloff in play of Taron and Benford, and the constant parade of defensive injuries. I'm going to throw the remote at the TV if we get gashed for another long run through the middle of our defense.
