2008-09: In 10 starts for the US NTDP Under-18 nationa squad, Campbell turned in a 7-0-0 record, a 1.71 goals-against average, and a .950 save percentage. In 21 starts for the Under-18 squad playing in the NAHL, Campbell logged a 14-6-1 record, a 2.52 goals-against average, and a .906 save percentage. Part of the gold medal-winning Team USA squad at the 2009 Under-18 World Championships.
2009-10: Campbell played for the US NTDP squad competing in the USHL. In 11 games, he turned in a 6-3-1 record, a 2.21 goals-against average, and a .917 save percentage. Campbell won gold with Team USA at the 2010 Under-20 World Junior Championships. Dominated the U18 World Junior Championships tournament. In six games, he posted a miniscule 0.83 GAA and a wicked .965 save percentage winning the USA the gold medal and himself the MVP honors of the tournament.
2010-11: Moved to Windsor of the Ontario League. Struggled early on especially and only played average for most of the season behind a fledgling defense and huge expectations. Very pedestrian numbers during the regular season, but in typical Campbell fashion, stepped up in the playoffs and helped spur the Spitfires into the Conference Finals. He was undone by the eventual OHL champion Owen Sound Attack, but it was a promising run. In his other big-game tourney, he was superb in the U20 World Junior Championships (1.70 GAA, .941 save pct.) earning the U.S. a bronze medal and was named the tournament’s best goaltender.
2011-12: In a disappointing season in terms of results, Campbell continued to display the potential of an elite goaltending prospect. He made his pro debut with Dallas AHL affiliate Texas as a 20-year-old following his second OHL season, appearing in 12 games and finishing 4-7 with 1 shutout and a 3.02 goals against and .912 save percentage. The Stars missed the AHL playoffs; finishing last in the West Division. Campbell played in his third World Junior Championship tournament with the USA, which finished in seventh place. Playing five of six games, Campbell was 3-2 with a 2.62 goals against and .906 save percentage. In OHL play, he was obtained by Sault Ste. Marie from Windsor in a mid-season trade to bolster the Greyhounds' playoff push; which ultimately fell short. In 46 OHL games (12 with the Spitfires), he was 21-22 with 7 losses in overtime and 2 shutouts. Campbell finished the OHL season with a 3.46 goals against and .896 save percentage.
Athletic goaltender with great reflexes. Never gives up on plays and competes hard on every shot. Sometimes he overplays the on-coming rush and can get into trouble. Has a very good glove and blocker. Stickhandles very well and is a fine outlet passer. Shows up majorly in big game situations throughout his career. Loves to compete, has a winning attitude, confidence and is always looking to improve. Consistency of any young goalie can be called into question and Campbell is no exception, maturity should ward off those untimely soft goals.
Potential: Starting NHL goaltender, like a more talented Rick DiPietro.
Expected to be the starter for the Texas Stars (AHL) in 2012-13.
