Hyuk. Ol' Dusty, running his pitchers into the ground.
The more I see of max effort pitching and the need to throw 95 to get a look, the more I think arm injuries are just an occupational hazard. Guys used to pitch in four man rotations with 20 complete games a year and 300 innings and not get hurt like these guys on pitch counts when 200 innings is an absolute workhorse. A big strikeout guy was 9K/ 9 innings, now that's decent. Branch Rickey was looking for a 2:1 K/BB ratio, now 3:1 is the yardstick.
The cost is arms.
