I'm not much into the post-war stuff. But, I like to pick up a few cards of the players I follow. I was noticing that several patch autographed cards contain letters that aren't even in the players name. For example, I was trying to grab a nice Christian McCaffrey auto patch card and the patch was a letter "K". I looked at every angle, every possibility and it's definitely a K. That being said, I'm losing faith that any of this game-worn patch stuff is even authentic. Did McCaffrey wear Luke Kuechly's jersey for a game?

Has anyone else noticed this?
