The number of listings for the playoff games are interesting -
- IU at Notre Dame: 600 - 700 listings
- Clemson at Texas: 1000 - 1500 listings
- SMU at Penn State: just under 4000 listings
- TN at OSU: 4000 to 5700 listings
Conclusion - Notre Dame has the best retention in terms of season ticket holders keep the tickets - Texas is next. PSU and OSU season ticket holders seemed to have bought tickets to sell them rather than using them.
So the tickets are out there for Tennessee fans to take them if they are able / willing to pay the price. If you assume on average 2 tickets per listing, that is 8,000 - 11,400 to be had.
