The other thing about pitchers that teams are doing is that have seemingly abandoned pitch mixes which protect their arms better.
I've read that sliders are the worst pitch for your arm but teams don't care anymore. They'll tweak the pitch to be more effective, even if it's worse for your arm, and then they'll have you throw it over 50% of the time if they think that's most effective.
Protecting arms is such an inexact science that it would be hard to calculate this, but I wonder if it would be worth teams exploring pitch mixes that are easier on their arms. Pulling these numbers out of my ass, but it might be worth using a more arm friendly pitch mix if it give your frontline starter a 40% greater chance to avoid major injury, even if it makes him 10% less effective.
I'm sure teams already do this when calculating their offers for FA pitchers. Gausman's fastball-splitter combo seems pretty arm friendly compared to a slider heavy guy.
Might be worth targeting and developing minor league arms with arm friendly pitch mixes as well.
