Just spitballing but maybe PSE had to overbid by a lot to get over reticence of having Buffalo host. Anyone attending the 2003 Frozen Four in Buffalo would have been appalled. Even though it's better now (though not that much better judging from takes I've read...and even then, I wonder how much effort was made to find places,) that lingering perception might have been a significant hurdle. You can bet there won't be another Buffalo Frozen Four.
