Fan reaction normally indicates that a team's supporters want players to be like them. They should champion the same causes, root for the same teams, and better not deviate from the norm. Ask Charles Johnson whether he learned about this the hard way. Despite re-signing a contract to stay in Carolina, wearing an Atlanta Falcons' hat was enough to justify a spate of negative comments via Twitter. Now Cam Newton has admitted to the same leaning.
In an article by D. Orlando Ledbetter of the AJC (via the Charlotte Observer), Newton self-identifies as a fan of the Atlanta Falcons -- except when the Panthers are the team playing them. The same team who told the Panthers to get the (expletive) off their field, and who Greg Hardy was willing to jaw with following the team's second game.
There is going to be a fan freak-out, that much is assured. This will get twisted into some sort of indictment of Newton's effort, or worse someone will pen an over-wrought statistical analysis to try and justify how Cam is throwing games -- it comes with the territory.
Since we are a bastion for intelligent fan communication our official stance will be firmly: "We don't care."
Newton grew up in Georgia, and it's natural that he would be a Falcons fan. Especially as a teenager growing up in the Michael Vick era where the agile QB was the league's biggest star. It's tempting to get bent out of shape, but it's not a slight on the Panthers or the organization.
