well duke would need to win 8 more national titles to catch UCLA.
Currently they are tied with carolina, indiana, and a number of other schools with 3. Kentucky has the most overall wins in college basketball, and with Roy Williams at UNC, Duke's dominance may be reduced.
Duke has been on a great run, but there have been similar situations with other teams. However, 10 more years like the past 10 and i would have to put Duke at the top of the list.
