Honest question, the top ten guys in the first two years you mentioned, how long were their careers after those max inning seasons? I'm not trying to set you up, I genuinely do not know. If those guys throwing all of those innings and CGs aren't lasting much longer, I would say it is shortening the life on their arms
If my pitcher threw 20 CGs and washed out of the league two years later due to blowing out his arm, I wouldn't call that a good strategy
