I remember when Ricky retired, you could walk into Marshalls & buy his jersey for like 4.99$ where it had been like 59.99 the week before.
I guess the only Dolphin jersey I'd return is Ronnie Brown's (the last one I bought). My other one's had pretty good careers here; Surtain, Madison, Chambers, Zach. I also have a Mike Vick Falcons jersey, Steve McNair Titans jersey, & a Ronde Barber Buccaneers Jersey. Really the only jersey I wear in public anymore is my hand-stitched, Mitchell & Ness Walter Payton throwback. If I buy any jerseys in the future, they'll be hand-stitched jerseys of retired players.
