I am looking to buy a couple of eric metcalf game-used jerseys, one falcons and one browns. The owner sent a photo of the Tag for the browns jersey, and says Tailored Exclusively for Authentic Proline by Wilson with NFL shield. Is that a retail tag? Jersey also has 75th Anniversary Patch. He also has a Chargers Eric Moten I am looking to get but has the lineman flap thing so am assuming that has to be a real gamer. No real tell-tale items to look at on the Falcons jersey, but if Browns is real and Chargers will assume Falcons is as well. Thanks for any help!
