Blue bloods are royalty... and royalty is defined by lineage... there is no greater lineage that that of KU... Naismith to Allen/Hamilton/Allen. From that lineage, sprang Rupp to UK in '30 and Smith to UNC in '66. The Royal Family (= blue bloods) are KU (starting 1898), UK (1903), and UNC (1910). There have other significant lineages that have sprang up independently (IU, UCLA, UL, UCONN, etc.), some multiple times, but they've ended... gone extinct.
Among all coaches, Rupp's performance is unprecedented (especially the rate at which he won from '47 to '67). During which we eclipsed KU and then UNC in all-time wins and won 4 championships. We are the gold-standard from Rupp on... our only deductions being the short tenures of Sutton and Gillespie.
