, runs produced is a teammate-dependent stat in that it includes Runs and RBIs, which are affected by which batters bat near a player in the batting order. Also, subtracting home runs seems logical from an individual perspective, but on a team level it double-counts runs that are not home runs.

To counteract the double-counting, some have suggested an alternate formula which is the average of a player's runs scored and runs batted in.



Here, when a player scores a run, he shares the credit with the batter who drove him in, so both are credited with half a run produced. The same is true for an RBI, where credit is shared between the batter and runner. In the case of a home run, the batter is responsible for both the run scored and the RBI, so the runs produced are (1 + 1)/2 = 1, as expected.
