LOUISVILLE, Ky. — With under a minute left in Friday night’s Sweet 16 matchup, men’s basketball senior guard Ryan Langborg banked in a deep three-pointer from the top of the key, to raucous applause from the swaths of orange gathered in the KFC Yum! Center. For Langborg, who has often been the hero of this year’s March Madness run, the shot gave him a career-high of 26 points.
