How do you write about losing a staple? Roy Williams’ retirement is reverberating throughout the college basketball world, as you’d expect from one of the sport’s greatest ever coaches and one of its few active (well, until now) Hall of Famers. But the sport has seen its legends come and go. Bob Knight’s retirement was just 13 years ago, and while that feels like it might as well have been the Mesozoic era with how much time has dilated in the past year, it’s basically yesterday on the timeline of college basketball. The late Pat Summitt’s retirement was less than a decade ago.
