If they let Pete Rose back into baseball, then they will have to let every other player run out of the game for gambling back into baseball, too. That includes the Black Sox, and I don't mean just poor Joe Jackson and poor Buck Weaver—I mean Chick Gandil and Swede Risberg, too. All of them.
Furthermore, they would never, ever to be able to ban anyone from the game permanently for gambling ever again, even if they bet on their team to lose. Unless they write new legislation specifying things like different penalties for gambling on your team to lose versus gambling on your team to win, which, if they do, then good luck to them on that, because litigating that kind of thing will be a time- and resources-intensive bitch. That's the beauty of the current legislation they have on it: they don't have to figure that part out. Gamble on your team. period? You're out, period.
And if it comes to all that, to where players and coaches can start gambling on games they play right out in the open because they'll be able to stay in the game even if they do, then I will walk away from Major League Baseball at that point. Because it will no longer be competition. It will be theater, and I will have no interest in that.
