With size, strength and skating ability David Broll has all the makings of a future fourth-line energy player. Broll tips the scale at nearly 240lbs, which makes him a monster to handle. With his wrecking ball style, Broll dominates opponents with thunderous body checks. He has a high work ethic and plays a consistent brand of physical hockey that will make him a nice fit to a team’s energy line. He’ll need to keep his conditioning in check and continue working on his defensive game to become a more effective pro.
