A physical blueliner with a heavy shot. Hellgren makes a decent first pass and is an average skater for a player of his size, but occasionally gets himself into trouble by making risky decisions.
A little on the lanky side, Hellgren could stand to pack on a few pounds which would complement his gritty game.
