Still think it's UK. In reality those two are the only true blue bloods. Everyone else has faults.
Probably the correct answer here....
KU---lack of titles
IU----dormant for 20 years
Duke---99% of their success under "K"---And yes, I know---Duke was solid before "K".
UCLA--Dominant in the 60's/70's--Only 1 title since Woodens last in 1975(1995).
I mean you could lay some claim with UK, with over their titles coming before 1959...Beat up on a football conference for 50 years...But, they have been extremely consistent.
Same with UNC----Had some great, GREAT teams under Smith, but just 2 titles; and got huge breaks in both of those---"The pass and The timeout". But like UK, extremely consistent---and could pick up title #7 here soon.
IMO, Kansas, Indiana, UK, UCLA, Duke and UNC will always be the standard that HISTORIANS look at, and compare to. But , over the years, schools have cemented themselves among the elite---MSU , UVA Nova, Louisville, UConn(though they have been pretty meh since Calhoun left town), Arizona...
Schools that have been solid, consistent recently---and even historically for period of time--- OSU, Michigan, Baylor(not historically)----probably could place Lousivlle in this spot as well...
Its a fun debate....But at the end of the day, schools like Kentucky, UCLA, UNC, KU, Duke and Indiana are gonna be the programs that CBB is defined by...And as bad as Indiana has been, their brand is still as good as anyone's. Just, well, a tremendous amount of bad hires----athletically, and admistrative wise.
