These games are meant to help UK improve. Some way. Any way. Samford gave UK’s defense — up to this point the clear strength of the team, a unit that head coach John Calipari said is defending at an efficiency so beyond its years it’s “not natural” — a new look and a test. See, coming into this game, Samford was supposed to provide a long-range threat. UK’s defense had struggled defending the 3; Samford was second in the nation in 3-pointers made.
