If i were to guess, its the Kopitar effect. Almost every revolving door in the few years on the powerplay with Kopitar has played the same. Slow, predictable, and telegraphed. The Half-Wall joke has its origin story for a reason. While Kopitar is a good player, he is very inefficient on the powerplay. He slows the game down too much. The point of the powerplay is to be quick and decisive in order to expose the lack of coverage the opposing team has down a man. Being slow and indecisive never opens lanes or exploits the man advantage you have.
Worst part of it all, Kopitar is never guarded heavily on the powerplay because he differs to passing way too much over shooting so the opposition rightfully blocks the passing lanes rather than encroach onto him.
