It will never happen. IBB will always be a part of the game, but hypothetically, I'd say make it a trade off. Pitchers can no longer give an intentional walk, but hitters can no longer wear armor above the waist. Sure, something for their feet or legs to protect from foul balls in the dirt is fine with me. Take away the armor that allows hitters to block off the entire inside of the plate and then we have baseball again.
Edit: Obviously a helmet is fine with me too.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
