How do you know when it’s over? There are signs, but they aren’t always easy to decipher. Coaches, even the best, get pushed out all the time before they actually want to go. North Carolina head basketball coach Dean Smith was able to leave on his terms, and later admitted he probably had a few more years left in him. The decision for Roy Williams to leave the Tar Heels wasn’t easy, and actually considered shutting it down after the 2019-2020 season and was eventually talked out of it. Williams’ wife, Wanda, tried to convince him to retire after the 2009 NCAA Championship. But all great coaches think they still have one more left in them, and getting North Carolina back to the NCAA Tournament in 2021 was enough for Williams to read the signs and call it a career.
