|Opponent||Rushing Yards||Receiving Yards|
While not on the chart, I did run the analysis to find the linear regression line and both the rushing and receiving yards had a positive slope. It is more obvious on the rushing yards and Iowa averaged a 7% growth in contribution by returning players per game. The growth on the receiving yards was more subtle: a little over 1% growth per game. Still, both categories showed improvement throughout the year, so my hypothesis was supported.
