NFL Shop. I think Eastbay has many on discount right now (even for players who are still active with their teams. Obviously a Jay Cutler Broncos jersey is cheap. But they also had Dallas Tony Romo jerseys and Giants Eli Manning jerseys reduced. They probably have some Phins jerseys.)
Speaking of Jerseys, I got my hands on the greatest jersey ever. A 1996 Dan marino Authentic Game Equipment jersey made by Wilson. IMO, the Wilson Authentic Game Equipment jerseys were the best ever made. I picked it up for $90 (it still had all original tags). I had one when I was in high school in size 44 (oddly, our local WalMart got a freak shipment in 1997 and sold them for $40...a steal for sure. They also had Packers Reggie White jerseys and Panthers Kerry Collins jerseys then). The size 44 does not fit me anymore (I'm 29 now) so I sold it on ebay earlier this year for a cool $100. (Not bad to have the jersey for 12 years. I probably wore it 100 times or so then I sold it at a $60 profit)
It took me a couple months but I found another Wilson Authentic jersey (just like my old one) in size 52 on ebay and won the auction. I know 100% for sure it is NOT counterfeit because
1.) the Wilson jerseys do not get counterfeited anymore. All counterfeits are of the Reebok models or Mitchell and Ness models
2.) The weight, color, stitching, etc is identical to my old Marino authentic jersey (which I also know was 100% authentic)
I prefer the old Wilson jerseys over the newer Reebok models and Mitchell and Ness models . IMO, if you ar egoing to wear a vintage Marino, then find a real vintage Marino (not a reproduction).
