Yeah, I have not seen him as someone who has been coasting at all. Not one bit.
He is one of the rare rookie big men I can remember who willingly set multiple picks on an offensive set, all the while ensuring that the picks actually hit. Not only this, but his picks seem to stick defenders in a manner similar to KG's (his legal ones, of course ). He also hustled really hard on the offensive glass a couple of times against Cleveland, and in my eye did better than Zizic.
What I meant by that, is a lot of his defensive ability comes from sheer athletic ability. He is not even remotely a polished defender, and has a lot of work in that area. That being said, his athletic ability is immense and he is still pretty good. If we can develop his game, to could be a real good player.
His workwork is a little shoddy, but he can make up for it, with his footspeed and athletic ability. He flails at shots, but can jump out of the gym.
I love his game and I am excited for him to come into the game each time. I think the sky is limit for him.
Don't confuse hustle with knowledge of the game. You can have great effort and not know what you're doing. You can be high energy and still be raw, which I present he is folks
A scouting report said:
Sometimes relies too much on his athleticism ... Still a raw prospect who, despite making a big leap in development his freshman year, didn’t progress nearly as much as a sophomore ..
