In 2014 I wore a CJ jersey to our game in Pittsburgh (two years off our Super Bowl and in the middle of a great season during which we'd belted them once already). There were a few flogs (though I'm pretty sure they could say the same thing about Baltimore) but for the most part there was plenty of respect - they respected me and the distance I'd travelled to see the game, they respected how good both sides were, they respected Joe as a QB and John as a coach, and they respected the Ravens as a strong franchise and a worthy rival for divisional bragging rights. And there have been plenty of people on this forum over the years who've noted similar experiences in Pittsburgh.
