Arizona and Baltimore are stupid is I think the main thing to take from McCarthy and Arrietta. Also Bundy in Baltimore event though it was literally his best pitch and did Arizona make Bauer stop throwing one too? Poor Bundy, had a wicked cutter that put minimal stress on the arm (I know it can put slightly more stress than a 4seamer but still nowhere near the stress of Cuvers, Slurves, Splitters, Sliders, and Sinkers). Baltimore forces him to stop throwing his cutter and instead throw more offspeed pitches (which I believe there was a bit of a conflict between the Bundy camp and Baltimore organization about this even before the injury). Then about 90 days later he blows out his elbow throwing more offspeed pitches. Will never know if that was the cause of the stress on the elbow but I could see the Bundy camp blaming the O's stupid organization for wanting a 100mph fastball guy with wicked movement to start ripping off tons of sliders/curves.
