Rick Carlisle said before Roddy Beaubois's debut in an interview that he knew his assignments better than anyone on the team and would be right up there with Kidd if given a quiz.
Actually, an NBA zone is very difficult to learn. The Mavs play a match up zone where only certain players are covered in certain areas of the floor, it's a zone with man to man principles that many NBA players never master and sit on the bench because of it. Clearly you know very little about basketball.... NBA zones aren't your simple 2-3 zones played in highs school, they're complex defensive schemes that force many talented players to sit on the bench when otherwise they'd be pretty good players.
To me.... you sound like a barea fan or a spurs fan that just wants Roddy to sit come playoff time..... Donnie Nelson just said two weeks ago that they expect Roddy to be a candidate as a top 3 player on the team THIS season.

They're serious when they say "he is the future of our franchise"..... NBA execs are consistently saying that about Roddy Beaubois. You can say he's a spark plug all you want I suppose, but you'll be rudely awakened come playoff time. The Mavs have big plans for him, they've repeated this on numerous occasions. Start getting used to the Mavericks with Roddy B.
