The definition of a late-bloomer as Dillon has grown nearly a foot since being passed over in the WHL Bantam Draft some years ago. Now he has major league size and knows how to use it. He’s a big, rangy blueliner with good mobility for his somewhat-recently acquired size. He exhibits good hockey sense and understands what’s going on at all times. Plays a physical brand of hockey and isn’t afraid to drop the mitts if the situation warrants. Strong, imposing. His puck movement is passable but he has a limited offensive ceiling.
