NCAA wants larger venues than NBA/NHL 15-20,000 seat arenas for the later rounds.
A total ripoff for fans unless they are paying top $$$ in the risers for later rounds, you can't see much in the domes.
Buffalo and Auburn Hills (Detroit next year) have been great to watch for most every other year for quite awhile for the first weekend.
Syracuse hosted the 16/8 a few years ago.
You were right at one time, but that's changed in recent years. Sweet Sixteen/Elite Eight has been going to less domes every year. And, now this year it was 4 arenas, no domes - Memphis, MSG, KC and San Jose.
I haven't gone to one of these since 2010, but what you described fit a bunch of them, especially when it's played in a non-college hockey hotbed. Those might actually be the best ones though for the people who really want to see the games. You've got fans practically giving the tickets away outside, those who got 4 seats in the lottery but only needed two. Even with all the improvements in Buffalo, it could very well happen again at this one. If you don't get the traveling fanbase in the game (North Dakota), attendance will be lacking.
I was wondering what teams travel for hockey. So many of the schools seem so small that I don't think they would have a big traveling fan base - UMass-Lowell, Denver, UM-Duluth, etc.
