We have the Players in the "Wrong" Uniforms thread and within that thread I've seen a few "Right Team, Wrong Uniform" entries. I thought I'd separate the two, because it is an interesting topic of its' own.
Here are a few to start the thread off with ...
Charles Barkley, Preseason 1992, Phoenix Suns
Matt Hasselbeck, 2001, Seattle Seahawks
Jeff Bagwell, 1992, Houston Astros.
