Yeah, I wouldn't trust that figure. We don't know where it is from or what year it refers to. We also don't know how the costs are apportioned. For instance, is the maintenance and upkeep of Thompson Boling split between all events or subsumed in the men's budget? All of the expenses which could be shared would have to be examined.
Then on the revenue side we have the big money from the SEC network which would not exist at all but for football. How do you apportion that income? The women's games are televised. Do they make money on those broadcasts? Are they a loss leader for the network?
This is the problem with a product that would not exist but for force being used to create an artificial market through Title IX etc...
