I admit to not knowing much about this, but after stumbling across it on twitter, I checked it to see if Iowa State was playing (they aren't). Looking at the teams in it, I'm assuming there is a long list of teams declining a spot? Is it a budget issue for most schools? Just ready for summer break? I could understand a perennial NCAA tournament program that had a bad season passing on it, but for schools trying to build something, I would think extra exposure is better than none.
