Yea, bags sorry.
I don’t know. Teams barely let guys pitch in the minors (5 innings max for most teams), they don’t let guys go more than 90 pitches in the majors, they know so much more about workload … and guys still get injured a ton because everyone throws max effort every pitch.
I’m not sure how to stop that without removing the amount of available relievers and making starters go longer as a result.
Maybe, just start with the hard pitch clock and see how that helps.
