There is fickle and fairweather and then there is fed-up.
After JJ, after Wanny, after Saban, after Camoron, after Sparano, after two years of Uncle Joe, you don't think people are tired of watching trash football? For ****'s sake, this team hasn't put 40 points on the board since 2003. We're averaging one 30+ point game per year in that span of time. Even extremely ****ty and traditionally ball control offense teams like the Browns have managed better than that over the past decade.
The problem with one-note mongos like DeathStar spouting "mediocrity" in every other thread is that they're not even right. The Dolphins haven't been mediocre, they've been bad. Our team sucks. I don't blame a single person who has given up their season tickets or refuses to buy merchandise.
And I like to think that what separates us from Redskins and Cowboys fans is not that we're bad fans or lacking in passion, but that we aren't as stupid as those people.
