Put me in the camp that buys tickets the day they go on sale. If you get good tickets, you are in a much better position if
1) you don't want to go to the sessions SU doesn't play in because good tickets are always going to be easy to sell (and you will probably be able to buy a good profit too if you are a capitalist).
2) SU gets assigned to another region and you need to sell your tickets (assuming you want to sell; if the tickets are good and SU was assigned somewhere far away, you might want to keep them and enjoy the scene; Buffalo is a fun place to spend some time watching college basketball).
The thing I am really mad about is that there were no tickets sold to the public for the Eastern Regional at MSG this year. This was to my knowledge an unprecedented thing. NCAA tickets have always been available to the general public, free from the corruption so many events are saddled with where promoters work in conjunction with scalpers to get maximum profits. I don't know if it was the NCAA, the MSG ticket office or both working together (that is my guess) but for the first time ever, I tried to buy tickets to an NCAA event the second they were made available and no tickets were available to buy.
Some journalist looking for a good story should investigate. This is a scandal waiting to be written about.
