Trying this late in the NFL season will be difficult to find a particular player of a team as well as the size you may want. Pickings are sparse until next season, but you CAN keep trying!
I know FOR SURE these people sell TRUE AUTHENTIC jerseys. I can DEFINITELY see the way the jersey is shaped(made for shoulder pads), the tackle-will #'s are a "flat mat" rather than shiny, etc. Also, several other jersey collectors recommend them - eBay store:

It's a sz 48, but obviously not an Owens:

PROJERSEYS! I dealt w/ him
personally, and will again in the future. They're low on stock right now, but at the beginning of the NFL season they have a plethora of teams & players. Check out the thread I made of the NO Saints Shockey jrsy I bought from him, and see what I mean:
