I haven't bought one of the new Nike jersey's, but if I did it would be an authentic and not some fake from china.
But the bigger issue is that there isn't a single player on the team that you can say you'd put his name on your back. Revis is going to hold out eventually, strong possibility he'd force his way out. Sanchez is a question mark. Tebow is for girls. No RB, no WR, no TE, no nothing but Mangold and there are tons of Mangold jerseys out there already. On D, forget it, Harris is played, and all of the rookies and second year guys are wait-and-see.
Can't believe I'm saying this, but my 2000 Nike Pennington jersey might be my only option this season. Can't be seen in my Bart Scott, don't feel strongly enough about any existing player, don't know enough about any new players.
