Nah. Putting it right on Grymes. For the most part he hasn't been the player he was before the NFL. He also seems weaker, even lighter, it was always a problem but the scouting report now is that its pretty easy to bounce off his hit tackle attempts. Kept my mouth shut for a long while about him but he's really been suspect out there. For a fast player he sure loses angles, coverage, can no longer make open field tackles. Also seems to be going for glory for instance in first half trying to bite for an interception instead of actually covering the play. His play is grating on me.
Theres no D schemes that compensate for a complete inability to make plays out there. This D also getting beat wide like rented mules. if they played the Argos today Wilder would still be running.
Really I can't think of anything this D is particularly good at.
