A smart two-way defender with good size and reach, Stone is a composed player at both ends of the rink. He is a strong puck-mover who makes a crisp first pass and can move the puck smartly and quickly up the ice. Keeps it simple in his own end relying on good positional and stick play.
Stone played almost a full season with Phoenix in 2012-13, and moving forward he should be considered a lock for at least a seventh or eighth defenseman spot in the NHL.
