It's going to be the Rams and either the Bucs or the Packers in the NFC Championship Game.
I say this because ...
1. Never underestimate the play of the quarterback during playoffs. Brady and Rodgers have been there - multiple times. The moment isn't too big for them.
Stafford has a great team, and he is a very good quarterback. But he's never been in this position - the frontrunner with a frontrunner team. And during the playoffs the game gets faster and the margin for error smaller. Brady is the master. He's been in more than 10 Championship Games. He's seen it all. And he hardly ever panics. That's a HUGE advantage.
2. Along the same lines, during the playoffs, the refs are a little bit more liberal. They let defenders rough up the quarterbacks a little more unless a hit is egregious. Kyler Murray's size is a disadvantage to him in the playoffs. The game plan will be to keep him in the pocket and clog the middle. And hit him ever time he releases the football.
I want to say the Cowboys, but they are a talented AND sloppy team. Offensive holding in the red zone continues to plague this team. And I fear that will be the same during the playoff.
3. Rams and Bucs have the better/more experience defenses, and defense wins championships. The Cowboys are still a bit inconsistent. Opportunistic but inconsistent. The Packers defense is improving. To get the most out of their defensive unit, the Packers need to run the ball more, play more ball-controlled football. But with Rodgers, I doubt they have the discipline to do so.
I think whoever emerges from the NFC is going to be Super Bowl champion. The road to the Super Bowl is a land mine, and whoever successfully navigates it will be all the better in the Big Game - just like in the 90s when whoever survived the gauntlet from the NFC (whether the Skins, the Eagles, the Cowboys, the Giants, the Bears or the 49ers) had it Easyville in the Super Bowl, so to, I think this is going to be the same thing this year.
