Rissling is a big, strong kid who shows a lot of grit, leadership, and character on ice. While he isn’t the most highly skilled of defenseman, Rissling brings some decent puck moving skills and defensive attributes to his game. He is also a physically imposing defenseman who loves to throw the body and drop the gloves when needed. He hits hard and plays hard and it has won him some recognition at the various levels of hockey.
While Rissling won’t beat out a lot of players based on skill he’s a leader and a character player that a lot of teams look for in drafting. A seventh-round pick wasn’t at all a waste on the big Canadian, and there is potential he could at his highest of projections be a bottom-pairing heart and soul style leader.
