After digging a little more, I'm leaning towards Murray-Boyles. His combine measurements are out: Collin Murray-Boyles has a wingspan of 7'0 3/4". This was recorded at the NBA Draft Combine, along with his height of 6'6 1/2" barefoot and weight of 239.2 lbs, and a standing reach of 8'10 1/2"
These are much better than Draymond Green. He is just barely 20.
Here is a scouting report from the Ringer, seems pretty fair, they only rate him the 17th best in this draft. But whenever I see the word "motor" in a report, my ears perk up:
It might not be a smart move trying to pitch the idea of Murray-Boyles in an elevator. He’s a remarkable defender who blends instinct and intelligence with strength, catlike reflexes, and lateral agility that’s unique for his frame.
But … he’s a tweener (strike one) who doesn’t really shoot (strike two) and whose obvious playmaking vision and instincts are stymied by a neutral assist-to-turnover ratio (strike three)—without the absurd athleticism that allowed a player like Zion Williamson to transcend such mortal limitations (OK, we’re done here, pal).
There aren’t too many success stories in the NBA with a prospect profile like CMB’s. That’s a significant barrier; teams are looking for precedents to follow. Just watch him play, though. It isn’t hard to imagine Murray-Boyles as a Swiss Army knife in the pick-and-roll on both sides of the ball. He can rumble into a blitz, creating havoc for the ball handler with his quick hands and broad frame; he can operate in the two-man game himself as either the initiator or the roller. He has the quickest hands in the class and would be a terror as a help defender digging at the nail. CMB’s brand of versatility may be unorthodox, but his particular gifts and outright motor could give shape to a defense.
On offense, Murray-Boyles is a handful in the post, where his power, footwork, and passing vision really shine. Of course, there aren’t many teams in the NBA clamoring for a 6-foot-7 post hub these days. South Carolina has given CMB plenty of room to explore the limits of his offensive repertoire—his usage rate is up there with the biggest names in college basketball. His on-ball creation is still a work in progress, as evidenced by his turnovers, but for a player with his oxlike frame, Murray-Boyles has shown the ability to vary his drives by changing speeds and accentuating either his touch or his bullying force, depending on the situation.
As reductive as it sounds, CMB’s trajectory could very well come down to his shooting. Draymond Green once had positional concerns despite outstanding defensive aptitude, but his gradual improvements from behind the arc (and a David Lee hamstring injury) ultimately helped him get his foot in the door at Golden State. It’ll be an uphill climb for Murray-Boyles, but teams have been looking for their own personal Draymonds for more than a decade, and CMB actually has the skill set, not just the chalk outline of one, to make it happen.
