Any surprises for you? Gotta love the schools that made it there one time.
Thoughts to ponder:
Whom has yet to qualify for NCAAs, but is getting or has gotten close in years past?
If the best coach [in your opinion] coached at [the worst school in the worst conference], do you believe they could make nationals? Name a coach and school combination that makes you laugh.
In your opinion, is it POSSIBLE for ANY D1 school to put together a national caliber team? It just takes five guys and the right coach to finish near the top on one day.
