All the teams who have the big travelling presence...

Are the old power teams. The teams that dominated in the late 70s to 80s in particular. Pittsburgh, Dallas, SF in particular who had younger fans at the time jumping on their bandwagon and who are working professionals now. Browns never had that power window at the right distance back in time, so thus they don't travel well.

Rams fans should be well represented in this game as a result I think.
