[...] The same could be said of Justin Brownlee, whose breakout this season has been rather unexpected. Brownlee does a little bit of everything; his combination of size, strength and athleticism makes him a versatile defender, impactful against all kinds of forwards, and a similar story is true of his offense. Brownlee's a decent shooter from outside, has a good mid-range game, will run in transition, and can make shots around the basket. He sometimes gets too shot-happy, and doesn't rebound as well as he ought, but when he doesn't play well, the absence is notable.
