So do you get what I'm doing? I'll be doing this for each MLB position. If you click on a player's name then it will take you to the baseballreference.com page of that player.
If you like pitchers that strike out a lot of hitters and do little or nothing else, Nolan Ryan is your man. Sure, Ryan put up some spectacular numbers - 5,714 career strikeouts, 324 wins - but those numbers were heavily shadowed by his 292 losses, his ERA+ of 111 and . . . oh yeah, his record 2795 career walks. For the best strikeout pitcher of all-time, his 2.04 K/BB ratio was pretty terrible. As was his average season record of 14-13. Ryan also pitched in the weakest hitting era of baseball. He wasn't terrible but I wouldn't exactly call him good eiter.
Don't be decieved by Koufax's 2.76 career ERA or his 165-87 record. This guy sucked the first few years of his career. If you cancel out his '62-'66 seasons, Koufax's ERA would be 3.94 and his 54-53 career record would be nothing special. His 1.90 K/BB was also horendous. How he won 87% of the votes in his Hall of Fame ballot is just way beyond me.
Cy Young did win 511 games but his 316 losses doesn't make that record as good as it should. Cy Young also pitched in an era where pitchers dominated and hitters didn't hit homeruns, which explains his 2.63 ERA. Was Cy Young a great pitcher? Yes, he won a ton of games and had great durability and longevity. The thing is, he is not the greatest pitcher of all time, no where close. There is a difference between good and great.
Take away Drysdale's '62 season where he went 25-9 and his career record is just 184-157. For a Hall of Fame pitcher, that is just down right terrible. It isn't like he did a lot of other things really good to make up for his record, he averaged 6.5 K/9 which isn't great or anything close to that and his 2.95 ERA was nothing extremely special in a pitching domination era.
A lot of people give McLain credit for being the most recent pitcher to win 30 games. I'll admit that it is impressive when you are the most recent person to reach a mileston but McLain did nothing outside of the '68-'69 seasons. From '63-'67, he had a 3.57 ERA. Then, in the '68-'69 seasons, he had a 2.37 ERA somehow. After those two seasons, he went back to sucking and had a 4.78 ERA the rest of his career.
