Really, the best way is to simply pick a program and just follow it. I chose St. John's because of their history, they're a NYC based school and their games are accessible (can always go to Niagara when they play). Plus, I don't like the big tier programs because, well, everyone is a Duke fan, but how many are Red Storm fans? Makes you feel unique in a sports world that is usually very homogeneous.
And the basketball is really, really good.
