I did that last year. Nah, not so much.
All NCAA purchased tickets are gone if you wait. Even if Tenn makes it back, you wouldn’t know what bracket days and game times they would have. We bought tickets last year for the 1st 8 games just so we could see everyone play twice (expecting the Vols to be there). Entirely to much baseball in that mid 90s heat last year. My lesson, wait and buy better seats after the field is set, just for the games I want to watch. I’d prefer to watch 4 games live, in good seats, and just over pay. Watch the others on tv in your air conditioned room or a sports bar if that’s your thing.
