There is just no way it can happen nowadays because of 5 man rotations insted of 4 man. Yes you are100000% right it comes down to how young pitchers today are coddled and taught to basically just be able to pitch 6 or 7 innings. With 5 man rotations the 1-4 guys get like 34-35 starts each and the # 5 guy gets like high 20s. for those 4 guys to all go 20-14 or better is impossible.
