I don't think he blamed the bad PP on Ennis, he said the bad PP is on DJ Smith (just like people used to blame our bad PP on Boucher) and also said he thought Ennis was a poor choice for the PP.
In all honesty, I'm not sure we have a lot of better options for the PP.
Tkachuk should be a mainstay in front of the net, and Duclair is probably our best shooting option. L.Brown is the center I'm most comfortable with, and Chabot obviously belongs, but that last spot has to go to one of Ennis, Tierney, White, Namestnikov, Pageau, C.Brown, Anisimov, or a Dman. Not sure there is an obvious answer. I guess I'd probably go with White or Namestnikov myself.
