The battle is often to the team that is the hottest and the healthiest. If Rams can avoid the injury bug as they have for the most part and they are certainly (the real Rams that is, not what we saw on Sunday) they have a very good shot at making it to the Super Bowl.
As for the Falcons. Their defense is above average, but they are not elite. Perhaps a notch below Tennessee's defense which I thought was very good when I watched it two weeks ago. I don't believe Atlanta is as dominant up front as the Titans were on defense.
Mc Vay has to do like he's been doing and running the offense through Gurley. He is the key.
Matty Ice Ryan is very good when he is not feeling the pressure but he gets the yips when there are guys in his face. We've seen that a lot. If AD can pressure Matt up the middle the Rams may have a huge day sacking the QB. Ryan is not as mobile say a Russell Wilson or Carson Wentz.
