Nurk is too mercurial*. Nothing necessarily wrong with that, we all have our moments of down/less up. But in as much as your average NBA player, it's not as beneficial to have them be moody or, to put it more bluntly, thin skinned.
As a person/dude? I'm sure Nurk is awesome. He just doesn't have the "dog" in him unless he feels slighted. But that "dog" can be a wolf, or a basset hound.
I kinda feel that Shaedon is a bit like this too. I wish he had Calebs confidence or hell, as much as I hate to say it, Kobe's killer drive *ON THE COURT*.
*for @THE HCP, mercurial means someone with unpredictable, rapidly changing moods or behaviors, often characterized as fickle, volatile, or erratic. I'll leave you to look up the other words as I don't have enough time in the day to continue down that dictionary rabbit hole*
