In the early days of Ravens message boards, you could not talk shit to a Browns fab without them crying about the move. I've been repping the Ravens hard ever since I was on 56k ya heard?! lol nah but I've heard it all from crying Browns fans. IMO their best argument and one that book I linked makes is that the immediate success of '95 expansion forced rule changes for how competitive a new team should be and the Browns were that newborn guinea pig. The Jags and Panthers whom both went to their respective Conference Championships a year after their inaugural seasons for reference.
Other greivances I'll hear are how shitty ownership can be, I drive by Snyder's mistake in PG a lot so I'm constantly reminded of how good we've had it since Art sold the team.
But whatever, that was a long time ago. Blind squirrel should've found a nut by now. They've been defying the odds for far too long. They're anomaly and they need a Sports God to break free from the loser black hole gravity of Leaveland. Maybe LeBron can learn to play for the Browns. He's their only hope.
