45 years ago today, Curt Flood filed the lawsuit that eventually led to free agency as we know it today. He sacrificed the rest of his career by refusing to accept a trade to the Philadelphia Phillies. He felt that a player was more than just a piece of property. He fought for the rights of free agency, even though he would never benefit from it. I wonder just how many players in today's game know about Curt Flood. Sadly, I don't think many do. If you don't know about Curt Flood and the sacrifice he made. Here are a couple of clips from Ken Burns and his baseball documentary.
