Good post, interesting topic.
Honestly, I see this as overly restrictive. To me this is just wanting to see the game as it was once played. Why should the game not change and grow, more pitchers means fewer tired pitchers or pitchers just throwing it over the plate to get them to hit it, that is really what has been eliminated. I agree this makes games take longer, but I would rather see them just eliminate the warm up pitches. You have 1 minute to get to the mound and make your first pitch from when the change has been made by the manager. Limit the time a manager has in a pitching visit.
Absolutely. Pitcher can pitch at their leisure within the clock, hitter can delay by 30 seconds ONCE per at bat unless there is an equipment problem. (i.e. a timeout). If he isnt in the box at all when the pitch is thrown it is automatically a strike.
require pitchers to face at least 2 batters rather than 1
Cant really do this because of injury. What you could say though is that if a pitcher only faces 1 hitter they are "disabled" and ineligible for 3 games (or something like that) and can only be replaced on the roster by going on the DL.
Require that at least two players must be on the infield dirt on either side of second base - eliminate the most extreme shifts and avoid 4 man OFs, which I suspect is coming for flyball pitcher/flyball hitter matchups
I see no point. The problem is not the fielding and pitching, but the hitters. If a hitter doesnt like hitting into the shift, learn to hit the other way. This is a rule that honestly is too easy to break and has unintended consequences. If a hitter puts themselves in a spot where they are this easy to predict it is their own fault.
starters would again be needed to go deeper into games
I will never understand why people want to see this. Why see tired pitchers or pitchers trying to hold on? Why make the game easier? Facing fresh pitchers is just more difficult, honestly I expect we are not far away eliminating the 5 innings to win rule and regularly having the first pitcher go 3 innings or so and back in a 3 days. That makes better sense to me and is a more exciting game.
I would add the loophole this year found by teams to "stash" relievers (and starting pitchers) by putting them in AAA limbo (sending them down but not really doing it, bringing them back up, thereby getting an extra roster spot). If you go down, you are in AAA for 15 days NO MATTER WHAT. Injuries dont effect the timeline, if a team needs you back they have to call someone else up, that is why there are 40 men on that list.
