-Agree with the universal DH and roboumps. It would be interesting to allow a guy like Ohtani to remain as the DH after leaving the game as a pitcher though (assuming the new pitcher coming in wasn't going to hit).
-I don't see any real argument against bigger bases, so if they really do reduce a few injuries and don't grow to ridiculous sizes, then sure.
-I like shift policing. It's entirely possible it has very little real world effect, but it will have a large optical effect on the game. It's really no different than rules regarding lining up in the NFL.
-I think I'm okay with the 7 inning double headers now. If they wanted to tweak it, maybe do 7 innings if a team is up by more than 3 runs or something, otherwise 9.
-I absolutely HATE the runner on 2nd in extras. It actually makes me want to turn the TV off for extra innings.
-Completely on board with the pitch clock. The batters stepping out after pitches needs to be properly enforced too.
-Limited pickoffs (at least that low a number) is horrible. If you want to make it 5 or something, I could get on board with that to prevent fringe nonsense. Maybe make all pitchers step off the rubber to throw to first (lefty or righty) if you want to increase stolen bases.
-Completely on board with expanded playoffs. You could also do something like requiring the higher seed to win 3 games and the lower seed to win 4 games in order to advance (first round only).
