Rushing yards can be misleading, as it’s a lot harder to get one yard on third-and-2 than it is to get five yards on third-and-15. This is where rushing yards over expected (RYOE), built using PFF charting data, can come into play. RYOE adjusts for game situation, how well the offensive line blocked and how well the defense is at defending the run. Both expected yards and rushing yards over expected can be useful when looking at running back prop bets, as we can see which running backs are being put in advantageous spots to run and which are getting a majority of the carries on their team because they are the better rusher.

· Taylor Has Been An Average Rusher This Year: After lapping the field in 2021 and having the most total rushing yards over expected, Jonathan Taylor has been an average rusher this season, adding 5.5 yards over what has been given to him.
· The Colts Can’t Run as Often as Last Season: Since the Colts were the better team in most of their games last season, they were able to get into advantageous run situations. This year, their neutral run rate has gone from 48% of plays to 55% of plays, so Taylor is getting the ball less often.
Tej's RB prop bets went 2-1 in Week 3, bringing his season record to 3-3 (-0.4 units).
· Rushing yards over expected was created using an extreme gradient boosting model (XGBoost). The most important factor in determining expected rushing yards is the number of graded and negatively graded blocks on a play. The importance is followed by yards from the end zone, number of box defenders, defensive strength, seconds left in the half and score differential.
· This model can predict 22% of the variance in actual rushing yards and has a year-to-year correlation of 0.21. A shiny app to explore RYOE for each player can be found here.
