Something that a number of people, including me, have tossed around is the frozen four monies. I can't find a reliable estimate of how much is distributed, though. ESPN has an article stating that from '81 to '91 the tourney dispersed an average of $100,000 per year to the tournament teams, with the highest year being about $650,000 to the field of 12. Since then, though, they've changed the format, and the monies don't go to the teams but to the D1 conferences that each belongs to.
So, does anyone know how much is being distributed now? I know the revenues have gone up greatly in the last few years....
