The three batter minimum rule seems to be getting the most push-back, which I understand as it is the most impactful, even more so than the DH. I'd be really curious to see how it played out though. Will it make guys who can ONLY go one inning marginalized? The staple 2000's bullpen of six one inning relievers and one mop-up guy couldn't work any longer could it?
Seems to me that would force teams to start carrying more traditional starters in the pen. So even without thinking about options, it would seem like guys like Romero, Gonsalves and Mejia would need to be on the big club instead of guys like Busenitz, Moya and Curtis.
Would these multi-inning BP roles for young relievers turn into a defacto waiting list for starting gigs instead of waiting things out in AAA?
Also, I'd have to think it would help extend the careers of aging starting pitchers. A Clay Buchholz or Ervin Santana may be a better fit than say Brad Boxberger. So aside from the decrease in strikeouts due to playing matchups, I'd think some of the guys who typically get strikeouts would be replaced by guys who don't.
If you have a BP made up of more guys than not that go multiple innings will teams go back to seven man bullpens? Or dare I speak it, six? With that 26th man could teams possibly go with a five or six man bench?
Also, it sure would make it more enticing to be a switch hitter again and it would decrease shifting. You'd still have shifting, but if you can't dictate righty/lefty matchups at will, it won't be happening every at bat.
I might also think this would actually help the traditional use of the starters. The good starters who don't have awful RH/LH splits won't be pulled for a LOOGY in the 5th, it will be more incumbent on the team to have it's best pitcher out there, not their best pitcher against a specific batter. 200 IP might become a realistic goal again and maybe we'll see another 300 win pitcher!
Plenty of questions with doing this though. Losing some strategy seems to be the biggest thing. I don't know though, current strategy would basically be shelved, but I think a more complex strategy would be developed. Would a team bait the other with a reliever to see if the other manager will use TWO of his bench players in the same inning? Do you save your best relievers for the highest pressure situation, or do you save him to face the big bench bat that you know the other manager is saving?
Originally at the top of my post I said I was just playing Devi's Advocate, but then I ended up talking myself into really wanting to see how this would play out. I like trying new things, of course that's with the understanding that I'm not opposed to dropping the new thing if it doesn't work out.
