Finally! Now we're getting somewhere.
I went back and watched some of the highlights from the game, and have some observations, which is what I think people wanted to talk about to complement stats:
These plays all highlight the moments where JL was performing well, which is great. He is a good LB, I don't think anyone is arguing that. Despite that, I do remember seeing him being lackluster on some plays in the Vikings game as well as previous games. If you notice this while watching tape please share it.
On a run for a loss by Peterson, JL clogged a hole and forced AP to reverse direction and was promptly stuffed. Something that doesn't appear on a stat sheet but indeed makes a difference.
On the first long run from AP, JL was left alone around 10 yards deep, and I can't tell where the safeties were at the time. A Viking blocker runs 10 yards down the field and is in front of AP to spring him loose. Dahl runs in from off screen and makes possibly the worst play on the ball in the history of american football and allows for AP to go the distance. Seriously, he overran him by about 6 or 7 yards.
In this play, JL was indeed a sort of "safety" for the play, most likely because we rushed 2 LBs(or 1 LB and a Mikell, hard to tell, but that would explain the lack of safeties in frame). The Vikings ran away from the blitz and were able to spring free the blockers needed to take JL out of the play. It's hard to pin that one on JL, as he aligned himself in front of AP, but didn't have any help. A bad play call? I can't say, but we were certainly set up to fail on that one.
Second big run. JL is lined up on the strong side and his orders are to stay on that side of the play. The play goes the other way, and our d line misses some tackles. JL not relevant to the play.
I'm not sure if this is actually the case, but if it is, JL Mikell should go back to his original spot and put JL back up close to the LOS again. We have 2 big new DTs for a reason.
That's all that NFL.com had for this game. From reviewing this footage as well as watching the game myself, I think that we might be too quick to judge JL individually without talking more about the scheme requirements. For example, I've often noticed how frequently I see Mikell blitzing this year, way up from last year. It would make sense then, in those situations if JL is playing deep as another safety, especially when you remember who plays opposite of Mikell. This would lead me to believe that he would be at the point of attack less.
