Nathaniel McMillan (born August 3, 1964) is an American basketball coach and former player who is currently the head coach for the Indiana Pacers of the National Basketball Association (NBA). He coached the Seattle SuperSonics from 2000 to 2005, and the Portland Trail Blazers from 2005 to 2012.
McMillan at one time played for one of the teams that he coached.
The text only says McMillar is a former player; it doesn't name any teams except those he coached. Maybe the algorithm thought he was a former player for the team he coaches.
