Note that when Roy first tied TTS a few weeks ago there was some discussion if they were tied for 4th or 5th, given Jim Calhoun's wins listed on Wikipedia.
I have since learned that the Wikipedia list for Winningest NCAA Men's Basketball coaches includes wins at all Division levels, and that Calhoun's totals include wins at DIII St Joseph (CT) from 2018-19 and 2019-20. His Division I wins total is 877.
