Despite plenty of hand-wringing from college basketball purists, expanding the NCAA tournament isn't the terrible idea many have suggested. In fact, yours truly has favored modest expansion for quite some time, especially and essentially if it keeps high majors from going their own way.
There hasn't been serious expansion for 40 years (when the tournament jumped from 32 to 64), and Division I basketball has grown substantially in that time. With everyone hunting for even more revenue, both internal and external pressures are pushing the highest majors toward something no one wants: separate tournaments of haves and have-nots.
