You could argue that Duke has as many quality wins as anyone outside of Texas.
UNC- Best win 2x Clemson only ranked team they have beat
KU - neutral floor win against USC, best conference win is at home vs OU
G-Town- Beat ND and UCONN at home ( both completely different teams now)
no quality road win
Memphis- Home win vs G-town and neutral cort win vs UCONN in November
Tennessee- @ Xavier, @ Miss ST, vs Gonzaga, vs Arkansas, vs Vandy
UCLA- @ Stanford, Mich State @ Wazzou
Indiana haha
Stanford @ Arizona @ Wazzou
Only team I can say other then Texas that has better wins then Duke is UCONN. Beating ND, Marquette, Indiana, Pitt, Syracuse and Louisville is better in my opinion.
