The Basics is the key to it. Kai, even when he was playing well(which I suggest has only been 2, maybe 3, times this season) seems to struggle with the basics of play. He does something "Amazing" which makes people think a class player is there, and perhaps there is, but this guy shanks and misplaces basic passes with a consistency you wouldnt expect someone who costs as much as he did to do.
The price is an issue. We spent "sure thing" money on potential.
