Wallinder is a player with large frame, but despite that, he shows good footwork and good agility as he can move smoothly in every direction. His first steps are not the best, but he has decent acceleration and good top speed, though he could improve these qualities, especially his first steps. He skates smooth when he turns both with and without puck.  He can play a two-way game and plays in all situations. While he doesn’t take any risks in his own zone, he always stands up against an opponent when he feels safe to do so. He seems to have good work ethic and works hard along the boards and is very effective with the poke checks because of his long reach. He could use his strength better when he battles along the boards. He shows that he has good vision and can read the play. He can also be a puck-moving defenseman, but he has some problems with puck control when he reaches his top speed and therefore loses the puck from time to time. His passing is not very creative; he likes to keep it simple and with that comes safe passes with good accuracy. When he is calm, he makes good decisions but when he is under pressure, he can tend to make bad passes that cause turnovers. Offensively, he has a hard shot and uses it in the right moments. He plays a confident offensive game. Overall, a non-flashy defenseman who can do the job without taking any risks.
