KJ might be my favorite guy on the team. While Dujuan, Hunter and Kevin are all supposed to be the "stars", KJ is the kind of guy who makes up for his lack of notoriety with huge amounts of effort and hustle. He's an absolute beast, which allowed him to do a pretty good job of playing in the low post last year despite only being 6'7" tall (which means he's probably 1-2" shorter in reality). That block against Missouri, while impressive, is actually kind of what I've grown to expect from him.
I also think he's the emotional leader of the team. When he gets fired up, it's contagious. He REALLY cares and is committed to the team.
