The only good option for the playoffs is to win the division.
A loss to KC would give them 5 conference losses. I'm too tired to look it up but can't imagine too many WC teams making it with 5 conference losses.
And that assumes a win over the Chargers.
There are too many teams in the WC hunt in AFC
Only hope is Dolphins drop a game or two and Josh owns them in the final game of the year
