There have been upsets in the NCAA Men’s Tournament before, but nothing like Lehigh (15) beating Duke (2).
Two observations. First, Lehigh outplayed Duke in both halves of the game. Duke was a bit lucky in getting a first half lead.
Second, Lehigh looked as good as, if not better, than any ACC team that has played Duke this year (besides North Carolina who basically pwned the Blue Devils twice). Lehigh’s defense was eminently capable of guarding Duke for extended periods of time and Duke never looked to have any sort of physical advantage. I mean C. J. McCollum got ‘em for 30 points! Used to be a time when only folks at UNC, Maryland, UNLV, Michigan, Kentucky, et. al. could do that.
The margin between the rest of the country and the just-below-top tier of the big conferences is non-existent.
