Dickinson is a skilled two-way forward with a really projectable frame. He looks bigger on the ice than his vitals suggest though he isn't all that combative. He has soft hands and a knack for puck protection with his long reach. Dickinson has a good, quick shot and is a very good skater. He has a good first step and can slam on the brakes with ease. He's a reliable backchecker and does not desert on his defensive duties. Dickinson is still a bit of a perimeter player and only shows flashes of ruggedness. His physical strength will come with time as he fills out that frame. He could be a special player if he develops his mental strength in synergy with his size and skill to help him fulfill his ultimate potential
Dickinson is one of the top forward prospects in the Stars' system. He is skating for Dallas AHL affiliate Texas in 2015-16 and is the team's third-leading scorer as a 20-year-old. Capable of playing center or wing, Dickinson plays with speed and vision and should be an impact player when he reaches the NHL. He projects as a second line winger, like a less talented version of Jeff Carter.
