The bowl revenue numbers above includes the playoff payouts which were massive.
However, many bowls struggled to put anyone in seats and are at risk of disappearing. Making a judgment on long term viability based on the first year is risky.
However the following bowls will need to do something to survive long term.
Each of the following drew less than a 2/3 full house for their game
10. Belk (Bank of America Stadium, Charlotte, N.C.), Georgia-Louisville: 61.9% - UGA is less than 4 hours from Charlotte and they could not fill that stadium?
9. Miami Beach (Marlins Park, Miami, Fla.), Memphis-BYU: 56.5%
8. Heart of Dallas (Cotton Bowl, Dallas, Texas), Illinois-Louisiana Tech: 54.29% - La Tech is a decent regional team
7. Hawaii (Aloha Stadium, Honolulu, Hawaii), Rice-Fresno State: 50.73%
6. Foster Farms (Levi’s Stadium, Santa Clara, Calif.), Maryland-Stanford: 50.42% - Stanford's campus is a 20 minute drive from this stadium and it was barely half full and it only holds 68K
5. Potato (Bronco Stadium, Boise, Idaho), Air Force-Western Michigan: 49.25% - Air Force is a good regional team for this event
4. New Orleans (Superdome, New Orleans, La.), Louisiana-Lafayette-Nevada: 48.8% - a Louisiana team in a La site and it is less than half full
3. Poinsettia (Qualcomm Stadium, San Diego, Calif.), Navy-San Diego State: 46.4% - SDSU playing a home game and Navy supports their teams well
2. Birmingham (Legion Field, Birmingham, Ala.), East Carolina-Florida: 42.05%
1. Quick Lane (Ford Field, Detroit, Mich.), Rutgers-North Carolina: 36.73%
Many of those bowls if that kind of attendance and likely terrible TV viewership persists may close their doors
