Bill James invented something called the "Similarity Score" which compares the stats of players across history. The formula for calculating the similarity score for two players is here: calculates the ten most similar players in history for every player with a substantial career -- just go to a player page on b-ref and scroll down to the Similarity Scores.

For example, Mets fans, the most similar player in all baseball history to Moises Alou, according to Similarity Scores, is --- Shawn Green!

Games: Alou 1,881, Green 1,913
Runs: Alou 1,075, Green 1,110
Hits: Alou 2,049, Green 1,970
2Bs:Alou 410, Green 440
3Bs: Alou 38, Green 35
HRs:Alou 324, Green 326
BBs:Alou 725, Green 730
