FWIW- here is what Gonzaga and Kansas did with their reseating for existing season ticket holders. Based on Kull's email, it sounds like SJU will be similar:
(1) You rack up "priority points" by making donations to the school, NIL contributions etc. You also get points for being an existing season ticket holder, the longer the better.
(2) Based on your "priority points", you are assigned a "seat selection window"- a specific timeframe in which you can select your new seats. People with the highest "priority points" get to select their seats first. By the time you get to your "seat selection window", your old seats may still be available, or maybe not.
(3) In the case of Gonzaga, you don't need to pay upfront for your season tickets until you see what's available during your "seat selection window". If you don't like what you see, you don't have to buy the tickets. I'm not sure about Kansas.
(4) Gonzaga says you cannot "reserve" your existing seats in advance - you have to go by the process above. Kansas allows it, but you have to make a huge contribution ($50k).
(4) This is for the existing season ticket holders. They get first crack at the whole process. Then when they are finished, other people jump in, I'm not sure exactly how they do that.
Not sure if SJU will follow the same approach. But I have a feeling they are not going to try to reinvent the wheel and will do something similar.
Fun times!
