Shayne Gostisbehere and Ivan Provorov have been great defensively and offensively. "Ghost" has already has an NHL career-high 50 points (10 goals, 40 assists) and is plus-13 after struggling with 39 points (seven goals, 32 assists) and a minus-21 rating in 76 games last season. Provorov has 32 points (12 goals, 20 assists) and has played 24:20 per game, most on the team. I think their season turned around when they started defending better. There definitely haven't been as many defensive lapses in the past few months.
Lastly, forward Wayne Simmonds, who hasn't played since Feb. 18, is expected to return to the lineup. The Flyers definitely missed his scoring knack (20 goals) and physicality, and he should bring it against the Penguins.
Minuses: Can the Flyers get enough production from their bottom six? It's been a problem most of the season. And while it's nice to have your top players contribute, you can't always expect that to be the case every game.
Goalie Petr Mrazek has all the tools but he's struggled recently. Following a 28-save shutout against the Montreal Canadiens on Feb. 26, he's lost three straight, allowing 14 goals in the process. The Penguins bring in a high-powered offense. Can Mrazek rise to the occasion? It will take time, but he's played great in some games and not so great in others.
The Flyers hopefully won't take many penalties because if they do, it may not end well. Philadelphia ranks 29th in the League on the penalty kill (75.1 percent); the Penguins rank first in power-play percentage (26.4).
