In that scenario: -One wouldn't expect his BABIP to continue, but it happened. And it was still based on his performance and not teammates. -One wouldn't expect his HR rate to happen, but it did. And it was still solely based on his performance and not teammates. RBI is different, while it did happen, it was greatly dependent on opportunity. I think your example would make a little more sense if you were talking about performances with RISP from year to year instead of RBI totals. Like a crazy BA or Slg% or OPS with RISP that is out of character for the batter that causes an RBI total out of whack with what he normally does? If we just look at RBI total, a guy could have 90 one year and hit poorly with RISP but have lot of opportunity, they next year he could hit great with RISP and have 65 RBI due to not so many opportunity. The amount of opportunities are completely out of his control. It's just not a good performance stat. Back to just RBI, Have you looked at the year Howard won MVP over Pujols? Howard had a few more RBI and many voters I heard mentioned that as a deciding factor. That he was a bigger run producer. Now look at their numbers with RISP and the discrepancy in number of PA with RISP. Who was actually better?
