Well, sure, if you’re not allowed to step off the rubber 12 times during an at-bat and walk around behind the mound, that’s just guaranteed Tommy John surgery, its obvious.
I guess I can buy-into the "everyone is throwing maximum effort" and "high spin" explanations.
But with all the advanced fitness & conditioning. Guys on pitch counts, fewer starts, etc- it's hard to understand why there are so many arm issues today. Maybe there isn't: just more visibility, recency effect and use of surgery.
As a 70's kid and big baseball fan- it amazes me that elite pitchers of that era like Palmer, Carlton, Seaver, etc commonly threw 270+ innings in a season and pitched complete games around 30% of their starts.
Not buying the pitch clock explanation itself. But maybe it contributes. Last night Jordan Wicks threw 94 pitches over 4 innings. Obviously a bad outing, but that's a lot of pitches in 60-75 minutes. And it's not uncommon for a pitcher with a quality start to average at least 18 pitches an inning.
