Not sure about last year but this year they have no depth. With no rotation and asked to win a lot of one-on-one matchups they are getting worn out. Our d-line is 9-deep which is unheard of. You get a physical freak like Rousseau on the field in the 4th quarter having played less than 50% of the snaps up to that point. McDermott's vision for the d-line is paying off big time.
