I needed to see it one more time to be sure, but Thursday confirmed (at least to me) that the Rams have a legit defense. The Rams defense is also physical and tenacious. That's four straight opponents the Seahawks have faced with good defenses, 3 of which played hard and with real tenacity. And, I think that's the key to stopping Seattle's offense (currently), tenacity and "fight".
It's easy to point to the Hawks defense and say "they're physical". But, the Hawks offense is just as physical.
To beat the Hawks, one thing's for sure, you MUST be ready fight HARD. The other team MUST be mentally and physically tough. I think the Hawks can get the Panthers to cry "uncle" as we saw Dallas and the Bears do last year.
Just a hunch...
