California Only State Posting More NCAA DI Hoops Titles Than North Carolina
North Carolina and Duke combined for four NCAA Tournament titles in the last nine years. The only time two different schools from the same state captured three consecutive NCAA titles was from 1960 through 1962 when Ohio State and Cincinnati reigned supreme. North Carolina was twice involved in back-to-back crowns with an in-state counterpart - 1982 and 1983 (N.C. State) plus 2009 and 2010 (Duke).
