I don't buy that you couldn't do a single city in the future. New York and Los Angeles could certainly handle it and I'm sure several other cities as well. Also, the option to do co hosts in Baltimore and DC. Don't want that to be every year but could be a fun way to do it every 5 to 10 years. I've never traveled further than Syracuse for the NCAAs but could definitely see the appeal of traveling to be able to see a city completely taken over by rabid NCAA fans and the ability to go to games 4 straight days.
Hope the flexible scheduling is not implemented. Seems like it will be something that is great for the big schools and a huge hassle for the mid and low majors. Just bring back the Bracket Busters instead.
