I may still have the old Jets jacket I wore in grade school. It's a small and has the old crappy Jets logo on it from the 80s. You can have it for 10 bucks.
Leon Washington is a good one to get too. Even Thomas Jones. Doubt they let either of those three players go anytime soon. Favre is obviously nice to have, because it will be a collectors item - and obviously even more collectable if the jets win a SB with him. Cotchery isn't a bad one to nab either, mos tlikely a lifetime jet. If your a "big boy", you could show some OL Love with a Nick Mangold jersey (they do exist). If you want defense? Rhodes is a good one. Revis too.
