I don't think Fox is the PP issue but I think keeping pucks moving quickly is more optimal than always slowing it down and letting the team set up their box. Poor use of the bumper and the down low areas to open up the bumper.
Pretty much agree with this. Fox should, in theory, have more power play points. He has elite vision, hockey sense, hands, puck control, and edge work. All of those are great assets to have as a PPQB. His biggest weaknesses, size and a lack of breakaway speed, are not necessary on the PP. However, he relies too much on his poise/patience, which, although it's extremely effective 5v5, isn't the ideal option on the power play. He also has a poor shot, which doesn’t help matters.
But even if he DOESN’T improve those things, we would be way more deadly if Zibanejad’s one-timer wasn’t this off and if we had better coaching. The issues with Fox are relatively small and I think he is still one of the league’s best d-men on the PP. I just think he could be even BETTER if he improves just a few small things.
