The Draymond Green comparison is lazy at best. Not every sub-6'9" power forward with guard skills is another Draymond; Draymond is an outlier and a unique one at that, who handles and passes like a PG, rebounds and protects the rim like a center, and plays all-NBA defense while posing as a threat from behind the arc (although, this year he only shot 30% from 3). He's like a combination of Boris Diaw and Dennis Rodman in the strangest, yet highly effective, way.
From his time with the Celtics, all I've seen from Yabusele is the ability to hit 3's and rebound well enough. The footage of him pre-Celtics is full of drives highlighted by quick crossovers and monstrous finishes in traffic. I don't see Yabusele's pre-NBA game translating to the NBA because his physical attributes are less incredible at this level of basketball. He has the weight and strength for sure, but his quickness and agility at this level are nothing to write home about, and that will prevent him from being the beast he was prior to the league. I thought he was a reach at the time and still feel that way now.
