KC is not an NBA player right now. Not even close. But the "potential" is there because he has shown a very broad skill set for a player of his size.
If I had to guess at a comparision, I would say the "up-side" is he could play like a poor-man's AK 47. Fill a stat sheet, get some points, and cause match-up problems by playing him as a tall guard.
He underperformed yesterday, no doubt.
