There's no job description per se, but if you wanted to get hired as an NBA referee, it might go something like this:
"Wanted - Good interpersonal skills, an ability to handle criticism, be in great physical condition and be perfect in administering and enforcing the rules."
Tre Maddox qualifies, though he admits he's no perfectionist. The North Las Vegas resident is in his second full season working as a referee at the game's highest level, and he knows the job is about trying to attain the impossible every night. But it doesn't stop him from trying.
