Biased I may be, but my vote goes to the Bruins under the John Wooden era. As a college team clearly they are at a disadvantage compared to professional teams as their players obviously don't stay for an extended period of time..making their accomplishments during this time that much more amazing. Here are some highlights from those Wooden years..
*four 30-0 seasons (1963-64, 1966-67, 1971-72, 1972-73)
*streak of 88 consecutive victories
*38 straight NCAA tournament victories
*19 PAC 10 championships
*149-2 record at Pauley Pavilion
*10 national championships, including seven in a row (1966-73)
I'd say the Celtics back in the day come a close second..and depending on how far we're stretching it, the De la Salle football team which went undefeated for a decade or whatever it was is certainly up there.
