My .02 fwiw -
This present set-up reminds me of the 98 playoffs where clearly the best two teams in the Championship round were the Vikings and Broncos, but the former suffered a horrible loss to an inferior opponent after (1) developing a big lead, (2) making a bad decision just before halftime, then (3) going on to lose in OT (cue the twilight zone music). The subsequent SB itself was no contest when the team truly lucky to be there got thumped by the team that wasn't. I expect history to repeat (except the final score won't be as emphatic if my take holds since in 98 the Broncos had a QB backing up a SB win the year before. Stafford doesn't have such confidence behind him, which you'd imagine automatically makes for a closer contest). More generally speaking, I've seen it so often across many sports that when the playoff bracket before the final event is littered with dog results, the final turns out to be one bridge too far for the legitimate dog involved and the fave rolls. Fair to say that the Rams are a legit fave here.
