I think it is true that they are graded after every game. The problem is...there is no consequence for failing. They just get retrained or something and sent out again.
They're not failing.
They never call traveling on los Nash, Wade, Chris Paul, the snitchster, or the messiah. Pierce will always get free throws on the upfake/charge.
But for the most part...(except for flopping) the rulebook will pretty much apply to everyone else...Less of course, the "human" element.
The messiah will never foul out of a game...Be able to protest anything relentlessly without accountability. The messiah is the brand and is to be protected at all costs.
The officials are sterlingly successful.
