Rundblad is an offensive minded defenseman with very good size and puck skills. He has impressive vision and likes to move the puck into the offensive zone with slick stickhandling and good speed. Handles the puck with confidence and has very good poise. A great option from the blueline, where he releases a fairly accurate shot and also find his teammates with tape-to-tape passes. Size and strength is good.
In his own end, Rundblad tends to not play it simple enough at times. He is a tad too creative and could also be more aggressive and determined in his play. If he develops his defensive game, he will be a high-scoring two-way defenseman. If not, he will still be a capable power play quarterback, but a potential liability in his own end.
