Villanova because it's a great program and it's the first team I really rooted for as a kid (I'm a PA guy and the 1985 tourney was the first basketball I remember watching and really caring about)
San Diego St. because living in San Diego would be really nice and it's a strong program
Vanderbilt because it's a good basketball school and a great academic school
Davidson because it's a totally different environment, still has really quality basketball, and has great academics (my wife went there so I've become a fan of the school and their hoops)

gives me a wide range of great choices :-)
