I do think that the players should be allowed to police themselves to some extent in certain situations like they did back in the day, however, throwing at hitters has gotten to a point where it's simply too dangerous. You've got guys exceeding 100mph on the mound and to some extent you're taking your life in your own hands simply by stepping into the batters box as a hitter. I'm firmly in the camp that says that this nonsense needs to go away. Where there is clear intent, penalties should be very steep. It's the less obvious scenarios that get harder to police. I wonder if there will come a point where they end up moving the mound back in order to protect pitchers from line drives coming off of bats and to give hitters more time to get out of the way of 100mph pitches. I hope they'd find a different solution for those, but I don't know what that would be.
