When the game gets tight, teams need two things from their forwards:
Players who keep the game simple, avoid costly mistakes, and generate production through a simple game (shots on het, traffic in front of the goalie, players there for rebounds). Cozens, Tuch, Greenway, Benson, and Krebs all fit this description.
Players who can create something from nothing. Peterka's speed is difficult to handle, and Quinn has the skills and vision. Thompson is in the category when healthy. This is where having a player like Zegras would be helpful.
Adams can add a player like Zegras, while adding more of the simple game players (examples are Dowd, Colton) and create a forward group which can play through though games.
