That's actually as probable as any long-shot scenario could possibly be. Arizona is probably favored this week, but if they lose they'll likely be underdogs the final 3 weeks. Dallas just got blown out by Philly and the Colts can score with anyone. Switch Dallas w/ Niners, Philly w/ Seattle, and Chargers w/ Colts and the same holds true for #4. yeah the most difficult part of that scenario is the whole 'Bears win their last 4 games'
