The differrnce between Jets and Browns fans: Browns fans can admit their team is horrible.
If the happiest day of your Jets fandom was a regular season win, it is an outright declaration that your team sucks.
I mean, the Pats blew donkey balls when I was young, but I could at least point to a win against the Dolphins in the playoffs to reach the superbowl or even the early rollercoaster Bledsoe years. And when my team was garbage, I could at least admit it.
