Re: Players who have played for less (to win)
Both of Hank's posts are correct.
However, I took the OP to mean star players. Role players take less quite often. But getting to my earlier point, someone like Haslem or Battier saw the makeup of the team (3 of the top 10-15 players in the league) and knew that they were signing on for likely championships.
In that situation, it baffles me whenever any player doesn't sign on there. Only reason they could go elsewhere is money and/or geography. In which case, fine.. more power to them. But never again claim that you value winning above all else.
