Okay, this is getting out of hand.
The Steelers are not a dynasty. They've won one of the last three Super Bowls (note: two words) and two of the last twenty-nine. NOT A DYNASTY.
They are not the greatest franchise ever. (Granted, I don't think much of Fleming's work as it is, but this was an exceptional piece of ... something.) They're not even the best NFL franchise, not by any method at all, unless you're counting "most wins by a team with a logo on only one side of their helmets."
People just need to stop. OMG BEST EVAR OMG should be reserved for sex, and even then, she knows you're lying. But it's a good lie.
Sports? If a team is the best of all time, time will decide that. Lazy sportswriters and athletes with no sense of history are hardly the ones to judge.
