As a stat, RBI can be an iffy one. You can be as good a hitter as possible, if your teammates don’t get on ahead of you, then you’re just not going to rack up as many as other players might. If you put up a lot of them, the odds are that you’re a good player, but a middling total does not necessarily equate to a middling player.
On the other side of that same equation is runs. Once you get on, you need someone to drive you home. You won’t find many more obvious examples of runs being iffy than Lou Gehrig getting zero of them against the White Sox on August 27, 1935.
