Sammy Sosa, Kenny Lofton, Mike Piazza, Kyle Lohse, Bartolo Colon, Reggie Sanders, Corey Patterson, Shawn Green, Shannon Stewart, Freddy Garcia, Rondell White, Jeff Weaver, Julio Franco, Neifi Perez and Armando Benitez. What do they all have in common? Aside from being Major League players, they are free agents. (Okay, I willfully left off Barry Bonds and he might be playing in the FPL - Federal Prison League - soon).
These guys need work.
So if there are any GM's that need a superstar to get your team over the top, why hire a rookie when you have these guys.
