It's not just jets we have to beat out. The ravens will probably finish the next three games 2-1 (worst case) so they'll have one of the WC's locked up.
That only leaves one slot for either us, colts, chargers, or the jets as it stands now. Assuming we tie the jets and the others win out, we'll still have to contend with tie-breakers against the others.
Still more scenarios include a collapse of the jags and the chiefs which could allow the colts and/or the chargers to win their division which would leave us competing against them for the final WC spot.
Who knows what's going to happen these next three weeks. All we can do is win out and let the chips fall.
