Brunson is the dynamic offensive version of TJ McConnell (a compliment).  He’s less athletic than Jameer Nelson in a way that will probably keep him from being the same kind of player in the pros.  Still, Brunson is about as sure of a bet as there is when it comes to looking at a plus backup point guard, and who might even end up starting for a few seasons.  Barring injury, I’d be willing to bet Brunson has at least a seven to twelve year career in the NBA.
Why?  Jalen Brunson not only can get to the rim despite his average athleticism (not counting put-backs, 49 of his 325 attempts have ended in an unassisted make at the rim), but he’s one of the elite shot-makers we’ve seen at all levels, with percentages rivaling a guy like Kyrie Irving.  His numbers this season are otherworldly: 71.1percent at the rim, 52.5 percent on 2-point jumpers and 44.8 percent from 3, despite much of his output being unassisted.  Add a three-to-one assist-to-turnover rate and you have the makings of a beautiful game.
So what separates A guy like Brunson from Trey Burke, A quadruple-A point guard who never really made it?  It’s the ability to get to the rim unimpeded.  Burke scored 55 unassisted baskets at the rim as a sophomore, but it took him 560 attempts to do so.  One out of ten attempts, the kind of number we see from jump shooters like Klay Thompson, or a player like Khris Middleton, who can’t get NBA separation and instead has to rely on making some incredibly difficult shots.  Whereas Brunson is closer to one-in-six attempts ending in an unassisted make at the rim.  And Brunson was even better as a sophomore, scoring 70 such makes in 338 attempts.
