CC under pressure?

According to Anthony McCarran, CC Sabathia may be feeling the heat from the Players Association to accept the Yanks’ record-setting contract. While on the record, PA reps deny the charge, McCarran’s sources seem to suggest that the lefty’s contract should set the market for pitchers. I doubt the union would exert explicit pressure on CC, but I can see why the rest of the union would want him to sign the best deal out there.
