Again you should never again get season tickets. I can see giving up tickets for financial reasons or moving away but to just give the away because you are unhappy is not acceptable. There are plenty of people who would love to have your tickets and IU don't need you.
Also I think you probably will be waiting awhile because I don't think Crean will be going anywhere anytime soon. I think what your expectations are is different than what Glass's is. I think as long as he keeps competing for a conference championships and going to at least the sweet 16 he will not be going anywhere. Fans might not like this but I just don't see Glass doing anything as long as Crean is doing what he did last year.
Also I do commend you on giving up your tickets and actually doing something about you unhappiness with the program. I do respect that you did more than just complain on a message board.
