2009-10: John McCarron skated in 58 games for the Lincoln Stars in his first full season in the USHL. After scoring two goals in 19 games with the Stars in 2008-09, McCarron chipped in offensively and was a physical force on a Stars team that finished with the USHL's second-worst record and was last in the West Division. McCarron finished the season with 7 goals and 19 assists and was minus-10 with 114 penalty minutes.
2010-11: McCarron was the second-leading scorer for Lincoln as the Stars were one of the USHL's big turnaround stories – finishing fourth in the West Division. In 60 games he scored a team-leading 24 goals with 33 assists and was plus-11 with 113 penalty minutes. In the playoffs, Lincoln was swept by Fargo in a two-game playoff series and McCarron was scoreless and minus-three with 4 penalty minutes. He committed to playing college hockey at Cornell in 2011-12. McCarron went undrafted in the 2011 NHL Draft in his second year of eligibility.
2011-12: McCarron steadily increased his productivity in his first year at Cornell – skating in 35 games as a freshman. Playing on a line with fellow freshman Joel Lowry, a Kings prospect, and senior Sean Collins, McCarron scored five of his six goals after January, including a goal against Michigan in the Big Red's NCAA tournament win, and had 13 assists; finishing plus-1 with 61 penalty minutes for the season. Cornell finished second in the ECAC Hockey League and won the conference's consolation game in the playoffs. After defeating Michigan the Big Red were knocked off 2-1 by eventual NCAA runner-up Ferris State in the Midwest Regional final. McCarron was not among the 210 North American skaters in Central Scouting's final rankings but was selected by Edmonton in the 6th round (153rd overall) of the 2012 NHL Draft.
McCarron is a big body forward that plays a smart game, uses his size well and has the physicality down low near the opponent's net. He doesn't appear at this time to have a big offensive upside but the strong winger has three more years of development at the NCAA level to improve his overall game.
McCarron will play his sophomore season at the Cornell university and is expected to bring more offense to the Big Red this year. He will play in the team's top six forward group and needs to use his size to open space for him and his linemates to be more successful.
