It comes down to who do you want to play? If the Chargers lose, they come here. If the Broncos lose, the Pats are the #1 with the win. If they lose and Denver loses, they drop to a three and play the Chargers, assuming a Jags win vs Titans. If they lose, Denver and the Bills win, they play the Bills in a 3 vs 6 game. So... if you want the #1, win. If you want to play the Chargers, win.
All this assumes a Jags win at home vs Titans. If they somehow drop that, then everything is a mess. I played with a convoluted scenario where Colts, Phins, Chargers, Jags and Jete win and that really fouls up everything, dropping the Pats to a 3 vs Texans.
TLDR: Don't rest.
