another aspect to look at:
Roy's coaching tree is absolutely horrible, lmao.
He isn't Dean Smith in that regard.
Here are the most notable members of Dean Smith's coaching tree: Larry Brown, Bill Guthridge, Eddie Fogler, Roy Williams. Brown and Williams both won national championships as college coaches. Guthridge took UNC to two FF's in 3 years. Fogler took Vandy to the Sweet 16 and had a stretch where he went 47-16 at South Carolina.
honestly, the best member of Roy's tree is Mark Turgeon and tbh, i'm not sure how much credit you can give Roy for Turgeon's success. Turgeon left Roy's bench in 1992 and didn't get his first HC job until 2000.
Roy Williams' bench is the only staff that Hubert Davis has ever been a part of. That is something I would be concerned about if I were a UNC fan.
