Wiggins is horrible. He’s been in the league for 6 years, and hasn’t noticeably improved. He just lacks drive.
The granddaddy of all advanced stats is PER. It’s offensively biased, but since Wiggins isn’t known as a defender, it will work for a quick and dirty analysis. The basis of PER is that everyone’s ratings are based on a league average of 15.0. All Stars usually start around 20, and superstars are usually high 20s to low 30s.
Wiggins career mark, for 6 seasons, is 14.. No, it’s not a typo. He makes a ton of money for a slightly below average offensive player.
