It works when you have a very talented player who is willing to act as a 2nd banana (Pippen, MVPau, Kobe at first), but when things go wrong, they go really wrong (Kobe and Shaq in 04).
Honestly, people pin the 12 Lakers failure on D'antoni (and Buss Jr.), but the situation could be a LOT worse with Jackson at the helm. Imagine how Dwight will react when he gets chewed out by Kobe and Jackson marginalize Dwight any further, Dwight can't even take a girl not responding to his text, he would go into depression under Jackson's style.
