I always like to check the contract length that a player has before I buy his jersey....they are kind of expensive if he's only gonna play there for 2 years.

If you go to any "FootLocker"(I don't know if they exist on the east coast..."Finish Line" is the same thing thing I think) they will order any jersey for you, and they usually have a list of retro-jerseys, might be worth checking out if you really want it. That is how I got my Derrick Thomas jersey after he died.
