Well there already on eBay.

The thing with the knock-offs is not the way they look necessarily, or the sizing, but it is the quality of the material and of the workmanship. I had two 'eBay authentic' Lavar Arrington Jerseys and I kind of knew they weren't real, but didn't know the difference until I got an actual real deal Reebok Chris Cooley. It is about twice as heavy, the numbers and letters are twice as thick and much strudier, the nylon mesh is of a completely different type and much thicker, all the stitching is more uniform and more tightly done, and, in my humble opinion, there really is no comparison. As the axiom goes, you get what you pay for and these jerseys are no exception. I would never buy a jersey from eBay again, but it is up to you. It will be cheaper, it will look pretty much the same to anyone who doesn't really inspect it too closely, but it will not be near the quality, so make your decision based on that I guess.
