13 of 20 teams were better OBP teams than HR teams (though some are arguably too close to call different). 7 of 10 WS winners were better OBP teams than HR teams. 8 were significantly better OBP teams than HR teams (5+ spots). 2 were significantly better HR teams than OBP teams.
I think looking at regular season stats makes more sense as it gets rid of SSS noise (i.e. one team has a game where they go bonkers and win in a unique way). What we do see is that only two teams weren't top 10 in either category. 13 teams were top 5 in at least one category. Average OBP ranking was 5. Average HR ranking was 8.
