The Maryland Terrapins are just the 8th tournament champion in 51 years from outside the state of North Carolina. Duke, NC State, UNC, and Wake would be a formidable quartet even if they were forced to play more than an hour or so from their campuses in the tournament, which rarely happens. Congratulations to the Terrapins!
Only one other "out-of-state" team also ousted 3 North Carolina-based schools to win: the '84 Terps led by coach Lefty Driesell and tournament MVP Len Bias. Here's the complete list of out-of-state champs, and the teams they beat on the way.
2004 MD -- (Wake, NCSt, Duke)
1993 GT -- (Duke, Clemson, UNC)
1990 GT -- (NCSt, Duke, UVa)
1985 GT -- (UVa, Duke, UNC)
1984 MD -- (NCSt, Wake, Duke)
1976 UVa - (NCSt, MD, UNC)***
1971 SC -- (MD, NCSt, UNC)
1958 MD -- (UVa, Duke, UNC)
***The 1st tournament played outside of North Carolina, in Landover, MD.
If Charleston or Richmond were to build a quality facility, I'd like to see the tournament moved out of North Carolina for a decade or so. Greenville or Orlando might do the trick with the facilities they have in place.
Non-NC schools have done better on the seven occasions the tournament was held elsewhere (4 times in Atlanta, 3 in Landover), winning twice. By my arithmetic, that doubles their chances -- .29 vs. .14. Time for a change?

Alternate years in NC beat every year, I suppose. The frequency will likely diminish further when BC, Miami, and VT get to vote, which is probably one reason why Coach K et al. complain about conference expansion.
