This defensive front isn't very good at containment. Lamar is probably going to run for a ton of first downs. That is the biggest threat with their offense vs our defense, in that we won't be able to get them off the field due to that and their physical line will wear us down.
Lamar also isn't a guy I consider to be a great passer, but he can put the ball anywhere on the field. So not blowing coverages while you're struggling to contain him is always a big focus. I'm of the mind our secondary plays with more discipline this year, though, so it would not surprise me if the back end does a good job. Think their TE is still out for them too, and if true that's a big problem we don't have to deal with.
Stuffing their ground game and containing Lamar will determine how we do on defense. And the offense can't just disappear. That's the other big worry for me in this game. Ravens defense is so hard on QBs that Stafford is going to have to keep that gunslinger personality of his in check. Don't force it when it's not there. Throw it away when you can. Play field position and get points when you're down there. Points are really hard to come by vs Baltimore.
