That type of info is pretty spotty overall, they can come up with a formula that predicts how much it took based on BB, K rates etc but I don't know if there is a good place to find exact numbers. Also I didn't mean to say Spahn would suck nowadays, he just wouldn't be a 270 IP pitcher. His career ERA+ is 118, Sheets right now has a career ERA+ of 116. Baseball is a very different game now and it isn't simple to just say why don't pitchers like today pitch like pitchers of yesteryear. As for SS I wasn't able to find easily sortable OPS lists before 1974 but here are the leaders by OPS at the position for a few years and how low in the leader board you had to go to have a sub .700. 74 - Toby Harrah .736 (4th best was .697) 75 - Toby Harrah .862 (4th best was a .679) 76 - Rick Burleson .748 (4th best was .679) 77 - Gary Templeton .786 (5th best was .691) 78 - Roy Smalley .796 (7th best was .689) 79 - Roy Smalley .794 (5th best was .697) 08 - Hanley Ramirez .940 (4th best was Hardy .821, 13th best was a .699) The position has definitely changed in recent years.
