Bystrom is a smooth skater with very good agility and recovery ability, He has good offensive tools and is a quality puck-mover in the transition game and on the power play. He carries the puck and joins the rush with confidence. Bystrom is still learning the defensive side of things and is susceptible to chasing the puck around and getting lost. He can make and take some physical hits but physically he’s a work in progress as he lacks pro strength.
Bystrom is in his first full season with the Texas Stars in 2015-16. Signed by the previous regime in Dallas in 2012, the former second round pick is skating in a lower pairing role for Texas. With several highly-regarded prospects in the Stars' system Bystrom is not likely to crack the Dallas lineup. His play with Texas suggests there is some potential for him as a lower pairing defender on a club that is in need of defensemen.
