I was going to mention that. It would be problematic for pitchers and how some teams use them. Absolutely an issue for relievers on playoff teams. It would be a problem, but teams wouldn't do this "loan" system or whatever if they were worried about that. They'd probably do a straight-up trade if they were worried about some "Dusty Bakering" of their young arms. I'm not saying this loan system is problem-free or likely to happen in MLB, but it has some advantages over the current system. Yes, in a sport like soccer, with a half dozen countries having their own elite leagues and 100s of teams participating in the process of loaning out a player to bigger clubs, or vice versa. MLB does not have an equivalent league anywhere in the world. The entire point of MLB is to try and make the playoffs and win a world series. We don't need a system that further rewards crap teams giving away their best players for money.
