You're basing this solely on attendance which is why you're on the losing side of the argument.
Did you know that when the Browns originally left Cleveland they already had a return scheduled? They left because they needed a new stadium and Tagliabue wanted a chise in Baltimore so Modell did him a solid.
And did you know the Browns' fan base was strong as ever even without a team?
Do you realize the Bills play a game a year in Toronto because their fan base stretches all the way to Canada? How is that a bad thing?
And that's just touching on the weak points you made, let alone the fact that these 2 fan bases have been around since before the merger.
What you're doing is basically comparing the Heat to the Lakers. Yes the Heat just won back to back but no way is Heat Nation fukking with LWO in terms of a fan base and overall franchise prestige.
Just stop, breh. You sound ridiculous and dont even know it. The Falcons?
