It's kind of funny how things go though. I cannot and will not cheer for Baltimore. I probably would be disowned from the city if I ever cheered for the Ravens, however, most Steeler fans actually feel for the Browns. It was always a close rivalry between us and them, and especially fun due to proximity but we hated that Modell took their team away and moved it to Baltimore. We couldn't even imagine losing a team.
The Pirates went two decades without a winning season, in fact, I was in 6th grade the last time it happened but we still loved our Buccos!
