Baseball pitchers are the new football players. Pitchers know that throwing max effort every single pitch is going to blow out their arms/elbows/shoulders, much like football players know that playing football is going to cost them later in life. GMs only want pitchers that throw 95+ with a 88+ slider. Velocity is the name of the game. Back then pitchers would conserve their stuff and not throw max effort every single pitch due to it being a long season and the expectation of going the full game. Pitchers were taught to "pitch" and not "throw," meaning mixing up pitches, changing speeds, changing arm slots, hitting your spots. All of that is out the window now with the max velo approach. I really miss the days that the starters throws 120+ pitches and goes more than 6 innings.
