Do any NFL fans own "Player of the Century" jerseys?

I don't but I have found out that they are knock-offs of Mitchell & Ness throwback jerseys so just be careful before you buy one because I heard that they are also illegal since they are fake and could be removed from any store shelf or from ebay if they are being sold. Just wanted to let my fellow NFL fans out there to be careful and not buy those crap jerseys, especially if you are looking for an authentic Mitchell & Ness, or authentic NFL jersey in general.
