2011-12: Gibson had an impressive first training camp with Anaheim and had a strong rookie season in his first OHL season with the Kitchener Rangers. Splitting time with OHL veteran Frank Palazzese during the regular season, he was 21-10 with 1 shutout and had a 2.75 goals against and .928 save percentage. After finishing second in the Midwest Division, Kitchener reached the OHL semifinals with Gibson handling the bulk of the goaltending. He was 8-7 with 1 shutout and 1 loss in overtime in 16 playoff games and had a 2.67 goals against and .938 save percentage. Gibson appeared in one game as a back up to Jack Campbell for Team USA in the 2012 U20 World Junior Championship. He made his lone start against Finland, stopping 23 of 27 shots in a 4-1 loss. The USA finished seventh in the tournament. He signed a three-year, entry-level contract with Anaheim in March 2012.
Gibson has proven to be a very mature goalie, developing physical coordination and mental toughness at a young age. His first junior season has been a smashing success thus far and he has shown the traits that made him the first North American goaltender taken in the 2011 Draft. While he is not a dazzling athlete, he has shown little if any major weaknesses in his game.
He is a complete goaltender who should ascend through the amateur and minor pro ranks quickly. Gibson will play out his CHL career and then there is nothing standing between him and a No. 1 job in the AHL with the Ducks’ affiliate, the Syracuse Crunch. Long-term he could be a No. 1A/1B goaltender, the type of battler the Ducks have coveted.
