Let’s hear the rule changes you think will improve your favorite sport. Two comments before your start:
First, let’s have real rule changes, no randomly exploding baseballs, no wild tigers roaming the court, do not suggest 10 rule changes that make American Football look suspiciously like Rugby.
Second, only suggest rules for sports you actively follow. If you’re an American who faithfully follows soccer every World Cup, pick a different sport to fix.
My rule is for baseball. It’s too slow, it can take over 3 hours, with a lot of that time being totally, ridiculously, idle. I propose ‘ready pitching’. Pitchers throw the ball when they’re ready, the 12 second rule applied strictly. Batters get one time out per at-bat. If they are unprepared because they have to adjust their batting gloves, and their hat, and their cup, and stare at the 3rd base coach for a while, they should step out of the box while the pitch is thrown.
