Football has been a money loser the last couple years due to poor attendance and that likely would not have changed much in 2020 (I am optimistic long term this will change). Assuming no football this season does not affect current marketing deals with Nike/Learfield and that UConn had no buy games this season, it probably won't affect AD financials much. The bigger deal is whether or not basketball happens given the significant uptick in ticket purchases, donations, merch, TV revenue from the Big East.
While no football season is a loss in ticket rev and the CBS Sports TV deal for this season, I think the numbers for the time being are relatively small compared to the cost of sending kids around the country to play football and paying rent to play at the Rent. You still have coach's salaries on the books and the "cost of scholarships" (quotations due to the weird accounting of it) but that should amount to less than the $10 million deficit of football last season. This again all assume other existing agreements at a top line AD level remain constant.
