McCarron was ranked 35th amongst North American skaters in Central Scouting’s final rankings prior to the 2013 NHL Draft.
McCarron has the hockey sense, work ethic, character and offensive skills to be player that could fit anywhere in the team's line-up. He has excellent puck protection skills down low and good hands around the opposition's net. The young winger loves crashing and banging on the fore check or playing in the dirty areas along with a willingness to drop the gloves when necessary. His skating is very good for a big man but still needs improvement with his balance, agility and acceleration. He projects as a possible power forward that could play in the top-nine at the NHL level.
McCarron will return to the OHL for another year with the London Knights. He is expected to play a role in the team's top-six forward group and take a step bigger forward in his development. Reaching his full potential could take a little longer than first thought but he is clearly a need on the Canadiens' NHL roster.
