They lose...you hate them.
Not quite the primary characteristic of a true fan.
Clearly you are not a Jet fan, so who came up short because the Dolphins won?
Chances are you are a Patriot fan.
Rooting for a team you hate to win has absolutely no positive quantum power, and may even upset the general order of things.
Now the Dolphins will kick the Brady-less Patriots asses and all will be well in the world.
It matters little as there is no chance that an AFC East team will win the Superbowl.
The Colts or the Steelers will represent the AFC.
The Panthers or the Giants will represent the NFC.
In no scenario do we find the Patriots or any other AFC East team.
