A skilled wing, especially for his size at 6-foot-7, Law presents great length and athleticism, which translates to both ends of the floor. With his frame, he should be able to defend multiple positions at the next level as well as create space to get his shot off.
Law is comfortable both shooting and driving off the dribble and has solid range—when his jumper is on, it's his greatest strength. When he gets going from three, although he's more of a set shooter from distance, he can swing games. Law has the versatility to score from inside, midrange and out and does a little bit of everything well.
Also a solid rebounder, Law is willing to mix it up down low. He makes quality decisions on the floor and boasts good passing ability. The all-around skill package is there, and he's an outstanding piece to build with going forward—the type of athlete on the wing that Northwestern hasn't really had in the past.
One thing to monitor is how Law handles potentially being the primary option on offense in a few years. With St. Rita, highly regarded teammate Charles Matthews often dominates the ball and during his time with Meanstreets, he was able to play off of Matthews and Tyler Ulis. Nevertheless, he's succeeded in that role and still puts up plenty of points. He had a very consistent junior year at St. Rita which helped build up the surrounding hype.
Law's move to the Chicago Mustangs for July AAU ball will let him be the first banana on a team that features mostly St. Rita kids, sans Matthews—a good opportunity for him to be the primary scorer. He'll likely have to grow into a starring role at Northwestern, but he won't be a ball-dominating type guy the second he sets foot on campus. He's shown a pattern of improvement throughout his high school career and I'd expect that to continue.
For a comparison, think along the lines of Luol Deng lite—able to impact the game in many different ways, doing everything pretty well and understanding how to fit in with his teammates. If Collins and staff are able to get the most out of Law, he'll be a big-time contributor for the Wildcats.
If Law is able to help pull in another recruit or two (*cough* Ulis *cough*), even better. I still think he could share a frontcourt with fellow 6-7 forward Josh Cunningham. But that's all speculation for now. Consider Law's commitment alone an instant win for Northwestern, and part of a fantastic start to the Collins regime.
