Final Four wide open

Would you care to guess who will be in the Final Four this year? Not too many years in my memory have things been more wide open than they are. Villanova definitely is the best team in the country, but they have lost a game and do have a weak spot or two; and in the Tournament you don't get a mulligan, of course. There is just not a team that I could put my finger on and say that I feel comfortable that it will make it to the FF.
