Brown has always had the physical gifts and determination to succeed; it's fantastic to see it all coming together. His improved body control, ball-handling, and finishing around the rim are super-impressive and things people might not have seen coming. He is literally unguardable 1-on-1 since his hesitation moves are so quick and he can go by anybody at will.
Most guys with his athletic profile aren't able to also create their own shot from mid-range or downtown (he is still a much better catch and shoot player from 3), but he seems to have all the moves in his arsenal. For years we were hoping he could be like Jimmy Butler - and don't get me wrong, that would still be great - but I think his ceiling has raised a bit.
And let's not forget the All-NBA level defense. I am happy to see Wiggins is finally clicking, but they are not even remotely close as players due to being on completely different spectrums as defenders.
