1. Eliminate the DH
2. Create a salary cap similar to the NFL
3. Have a "franchise" designation or something like the NBA has where a players team can offer more money than any other team so that teams like the Brewers or A's that develop talent can actually keep it.
3. Gag all "baseball purists" like Bob Coatas. I am so sick of the "this is the way we always did it, so we must continue to do it this way" bs. The Wild Card is awesome, as is interleague play so shut the hell up!
4. Managers and coaches are not allowed to wear uniforms anymore. They aren't playing, so they shouldn't dress like they are. Let them dress like NFL coaces...polo shirt, jacket, or some other logo apparel.
5. Beer prices should be capped at 3 bucks.
6. Eliminate a lot of the unwritten rules. If someone is throwing a no-hitter, the other team should not feel compelled to not bunt to break it up. Afterall, you are supposed to play to win, not let the other team win. If it was game 7 of the World Series, would you follow this "unwritten rule??" Same goes for stealing bases when your team is way ahead.
