It started with Curt Flood. Messersmith finished it. No team could own you forever. Let alone the loyalty factor. Messersmith did get his $1 million dollars. The very first to get that amount of money. Now, some baseball players are getting long term contracts, upwards to $427 million dollars. Mike Trout of the Los Angeles Angels, is one of them. He is compared, to the late Mickey Mantle of the NY Yankees.
Thanks for the clarification. At any rate, team loyalty is not what it used to be. One can start playing with the Yankees and end his career with the hated Red Sox.
