I don't value stuff that's made up in other people's heads and varies skull to skull. That's true.
Yet, even if you want to make a chemistry argument here, what is it? How does it manifest itself? When Kemba's not on the court, the Hornets are a mess. When he's on the court, they're almost good. Tony Parker, famously good at chemistry/mental part of the game, hasn't been able to get anything out of this train wreck. Kemba is carrying his team. Without him their chemistry is hazmat. Earlier this season you were trying to insist they needed to play more Malik Monk, who's useless.
So, aside from you saying so, I'm not seeing any issue with Kemba other than he's been saddled with a terrible team.
