I've done this on espn playoff machine a bunch of diff ways

1. Rams must win out
2. Green Bay needs to lose to either Carolina or the Bears or also lose to Titans
But a Titan loss by itself doesn't help
3. Aints need to lose twice
Best chance obviously is against Chiefs and Vikes

Footnote
Unless Seahags lose to wash and whiners we basically have to beat them to win div
