Thanks for all of the feedback
Here is some additional data that includes some of your comments
We added a revenue column. Was able to ind revenue average for football teams. Moved most of the funding for robotics teams into the revenue column since school only pay a limited amount for robotics. For all other sports we made their revenue a fixed amount of 2k per year.
We added pay for the large robotics team coaches.
We changed the graduation rate of the two least leveraged sports to graduation rates from the NCAA web site. For all other sports we left graduation rate at national average.
Again here is the data for the new chart
