Those 20 games really change the complexion of the game though. How many teams in the past few years have gone on a tear/imploded at the end of the season? It's a long season about endurance, not being hot at the right time. I also disagree with a 7 game LDS. Just doesn't seem meaningful.
I do agree with an expanded strike zone. I would also like to see more transparency with the discipline of umpires. Yes, they are human and mistakes are to be expected, but some of them were out of line this season. And I'm not talking about blown calls. With that said, I don't believe instant replay should be expanded beyond fair/foul of HRs... although maybe a general fair/foul determination in the playoffs.
It would definitely change the game a bit, but I'd rather have a more robust postseason than the last 20 of the season. It would be a huge change. It also won't happen.
My issue with the umps is that they are all so different. The strike-out to walk ratio is all over the place. With pitch f/x the plate ump should have an earpiece that beeps when it's a strike or at least mlb should use pitch f/x to audit umps.
I also would looove to see mlb find a way to make winning the division more important. The wild card is great, but the Yankees and Rays were tied for first headed into the last game of the season and for the most part nobody cared. Some ideas that have been tossed around are adding two more wild cards and giving the division winners homefield advantage throughout the first series.
It would also be neat to see the draft replaced by an auction format.
These are all dreams. MLB won't change, but it would sure be nice.
Truthfully if they just games down to 90-120 min, i'd be happy.
