It's been a rollercoaster ride for Jalen Green as a Sun, which isn't much different from how his career as a whole has looked. In the limited time he's been on the court this season, it hasn't been great (most of the time), averaging 17.2 PTS on 49.4 TS% with 2.6 AST (to 2.2 TOV).
When he's on, he shows glimpses of being a superstar in the NBA, like the recent 5-game stretch (from March 6th to March 13th) where he averaged 28.8 points on 63.3% true-shooting with the Suns going 4-1. The problem is, when he's off, he'll bring the team down with him.
