Were I ranking the match-up from "easiest" to "toughest," it'd be:
1) Detroit: Though the Lions are a very good team that's had a good season, they're still young and don't possess a lot of playoff experience outside of Goff (who is just as likely to melt under the spotlight than shine). I could easily see them making some of the mistakes the 2017 Rams did in their WC match-up against the Falcons. 50/50 shot.
2) Dallas: Both teams are different from their match-up earlier in the season where I think the Rams played their worst ball of the year. Though the Cowboy D played the run well against the Lions recently, they've shown some vulnerability in that area. The Rams, OTOH, have begun to emerge with their rushing attack. Whereas we don't know how the Lions will react to the pressure of the playoffs, we've seen Dak and the Cowboys pucker up. A little less than 50/50 shot at winning.
3) Philly: I don't care how the original author believes the Eagles are playing right now...they are a bad match-up for the Rams. They still have a solid defense and I don't think our defense is disciplined enough to keep Hurts in the pocket or stop all of these late-season secondary busts for explosives. Don't like our chances at all.
