LeSean McCoy is going to get involved with every single fanbase in the NFL, and there's nothing we can do to stop it.
First we saw him in a Raiders vest this morning, and imagined everybody in Philadelphia getting super mad at him. But after he got the Raiders gear off and got his Eagles uniform on, he made his allegiance in the NFC East rivalry between the Eagles and Redskins clear:
a) Don't show up at games with flags of other teams and taunt players with them. They will either ignore you or clown the hell out of you.
B) LESEAN, YOU CAN'T TAKE PEOPLE'S THINGS LIKE THAT JUST BECAUSE YOU'RE AN ATHLETE! That thing still belongs to him and you should give it back. Although having to buy a new flag is a small price to pay for an awesome story like "LeSean McCoy stole my Redskins flag" if you ask me.
