I have had a crazy thought about baseball for a few years now. Most won't agree with it, but it would fix many problems in the game.
Drop the number of balls for a walk to 3.
Pitchers will nibble less, and pitch to contact more. This will result in fewer pitches thrown, and potentially fewer arm injuries.
It will speed up games and make them more offensive oriented for casual and younger fans with short attention spans.
We will see fewer power throwers with absolutely no control. All those arms who can reach 100 mph, but can't find the strike zone will be pushed out of the league, and injuring fewer players.
There will be fewer balls thrown AT players to push them off the plate, or as warnings, ********. The rule will not prevent intentionally hitting someone, but warning throws will add up very quickly.
Each pitch will matter, and umpires will stop getting away with awful calls.
