The problem with the eye test is that it is subjective and hinges on the BBIQ of the person watching along with whatever biases they have. That's why I try to avoid appeals to the eye test. You ask a fanboi to tell you what the eye test tells them and they'll usually come up with something disconnected from reality. That's the benefit of objective metrics. It's not perfect, but it's pretty good at eliminating bias.
I think this goes for a lot of our guys actually. It comes across more like a lack of defensive awareness more than any actual physical limitations. Often you'll see our players (especially Green and KPJ) focus on the ballhandler instead of the man they should be marking, and kind of float between helping or marking their assignment. This usually leads to either their man being wide open or everybody scrambling to rotate, ultimately leaving most everyone out of position. Seems like a fundamental flaw in the way we play, and something coaches should be rectifying.
Au contraire. That's exactly what he's proving to be. On and off the court. Like DD said, we have quite a story unfolding.
