I don't think you can make definitive comparisons across eras with pitchers. When you compare guys with 200 IP with guys like Newhouser, Lolich and McLain who had close to 30 CG and over 300 IP, It's apples and oranges. I am not saying those guys were better, just that it was a very different set of circumstances. You can say that those pitchers couldn't do that in this era where every pitch is thrown with full effort and you'd be right, but if they were confined to 7 inning starts, they would have had much better rates than they did. The question is which pitcher dominated his own era the most? I think Skubal, McLain and Verlander and some others were all incredibly dominant in their best seasons.
