Well aren't they all? Wins for pitchers? Only granted to a starter if he goes 5 innings... but a pitcher who comes in after 2 outs on the first and records only one out can get the win?
.OBP.... guy on third, one out, tie game, bottom of the 9th... you hit the sac fly and win the game. But your .OBP goes down?
RBIs... bottom of the 8th, bases loaded., no outs, tie game. You hit into a double play, and the go ahead run scores. Your batting average goes down AND you don't get an RBI.
But if you get hit in the face with a pitch with the bases loaded... RBI!
WAR is a very useful stat for measuring a player's production compared to his peers in a given season. And thats the name of the game, when it comes to spending on players within a budget.
