An outlier season is a season that is statistically divergent from other seasons. There are historical examples of players having outlier seasons; take Isiah Thomas’ 2016-17 season. Isaiah averaged 29 points per game that year and never got above 22 PPG before or 15 PPG after. Kendall Marshall on D’Antoni ‘s 2013-14 Lakers averaged 8 assists and points per game and hasn’t looked like an NBA player before or since. Dorell Wright, Joakim Noah, and others have had positive outlier seasons, depending on what statistics you use. (I’m expecting there to be a lot of “well actually’s” in the comments, and I welcome them.
