eRBI – Expected RBI
Represents the number of RBIs that the league average would have generated in the same amount of situations a given player was presented with during a season.

aRBI – Actual RBI
Represents the RBIs that a given player actually drove in, which eliminates RBIs accumulated on walks or errors in the field - sacrifice flies and groundouts are still included.

aeRatio – Actual RBI over Expected RBI
Represents the amount of actual RBIs that a player earns per each expected RBI. A ratio above one shows a player drove in more runs than expected, while a ratio under one shows a player failed to drive in more runs than what the league average would be expected to.

ROLA – Runs Over League Average
Represents the variance between a player’s actual RBI and their expected RBI. A positive ROLA shows a player who drove in more runs than expected, while a negative ROLA shows a player failed to drive in more runs than what the league average would be expected to.

Additional Notes
Players must have accumulated at least 25 eRBIs to be considered
Only non pitchers are eligible
