They'd never face each other, but Id pick GB against whoever wins the NFC south, too.
Call me crazy, but it wouldn't surprise me at all for this Packers team to go on a bit of a run - theyve played badly enough to give their key starters a bye week next week (Vikings game means nothing for them), so they'll be as healthy as they possibly can be headed to a likely road playoff game against the Bears (barring some week 18 seeding adjustments). I'd pick the Packers to win that game since they dominated that team 6+ quarters they've faced them over the past few weeks. Then they'd go to the Rams and play in an essentially neutral field environment in good weather conditions - i can see that game turning into a shootout the Rams would win 75% of the time, but thats not 100%...
