Taking info from Sarge's Graph, here are the ticket and dollar losses (assigning a value of $50/season ticket X 7 home games) since Ash started coaching at RU:
Loss of Tickets from Previous Season:
2017 - 4,466 (4,466 cumulative) $1,563,000 lost revenue
2018- 1,103 (5,569 cumulative) $1,949,150 lost revenue
2019- 6,124 (11,693 cumulative) $4,092,550 lost revenue
Total lost ticket revenue under Ash $7,604,700
That number is fairly conservative, as it does not include parking an concessions.
That figure exceeds Ash's buyout after this season ends. And that does not even take into account that Ash will get a DC job substantially mitigating what he is owed-- that buyout figure will go down by at least $1,500,000.
