If the CBA has a provision added to limit player moves teams will be short players, specifically pitchers, constantly in the current system. It makes a lot more sense to keep throwing darts as opposed to being forced to send the same ****** pitcher out there endlessly. They did the right thing by limiting the number of times a player can be called up and optioned back over a season (5 times). However one thing they should do is limit the amount of times a played can be DFA'd by a team, he elects to be a free agent, and then the next days signs back with that team and is selected a day later again. I'd call it the Carlos Carrasco Rule.
