Was talking with a Penguin fan last night about the PO series last spring. He said that the Pens knew that they could pretty much count on being able to enter the offensive zone every time on Ghost's side of the ice and that was part of their offensive plan. Pass it by him because his stick D is not that good; run over him because of his size and out grind him in the corners and in front of the net. Its hard to argue against that strategy.
Since that is the case and some other teams have followed that tactic with success, if Ghost is going to be effective on defense he needs to have a strong physical partner with him like Morin or Myers can be. Neither Provorov or Sanheim are physical enough to fill the bill. For some reason, so far, Ghost and Gudas hasn't worked.
Its not that Ghost is a bad player, he isn't an has serious offensive skills, but his game also has serious flaws that need work and the proper partner. With all of the defensemen that are coming through their system, IDK if the Flyers have the time and resources to work that one through. Probably better to move him on to another team that thinks that they have the answers.
