Iowa led the nation in wrestling attendance for 18/19 averaging 8526.3 per match, ISU was 6th at 3569.7 per match.
Tickets for Iowa are $20 for Penn. State, $15 for OSU and Ok. St. and $12 for the other four meets, season tickets for this year were $85.00.
I could not find the data for ISU, it did say season tickets were $85.00 for this year, but no breakdown by induvial meet.
So both schools are losing their ass on wrestling.
"ISU sold $180,000 in tickets and spent, $363,250 for wrestling"
Losing about $180k on one sport for a department that has revenues of over $88 million* isn't "losing their ass" as you said. Yes, they lose money on the sport overall but its not bleeding us dry by any means.
