Bill James REALLY doesn't think much of that MVP vote, lol. He mentions it in his writing often.
I don't think it's anything against Versalles, as his production was there. Leading the league in total bases is legit. Maybe less so when you lead the majors in plate appearances, though. Led MLB in striking out as well.
The only 2 players with a similar WAR were pitchers. No hitters had any kind of big power season, either.
There are many more severe MVP votes than that one. Not sure why James feels the way he does. Possibly that it was 1 vote away from being unanimous?
