This INSANE idea that guys in the best shape of their life can't pitch a bit more is exactly that, insane.Do you realize that Sears and every starter in baseball has a Bullpen session in between starts. Pitching 1 innings is actually less strain than a bullpen session.
Pitchers but probably more their agents, created all this and it worked, just like pro and college football coaches created this insane idea that they work 234 hours a week.
