Gibson has a .923 save percentage for his NHL career, the highest among goaltenders to play at least 150 games since 1955-56 (when shots on goal became an official NHL statistic), ahead of Hockey Hall of Famers Ken Dryden and Dominik Hasek, and Tuukka Rask of the Boston Bruins (.922 each).
He is 93-55-20 with a 2.29 goals-against average and 16 shutouts in 178 NHL games (171 starts), and 11-13 with a 2.80 GAA and .912 save percentage in 26 Stanley Cup Playoff games.
"I believe in John Gibson, as does everyone in the organization," general manager Bob Murray said. "This is obviously a major commitment by the club, but one we feel strongly about. John is equally committed to being a Duck. He is only now entering the prime of his career, and we are all confident his best is yet to come."
Selected by the Ducks in the second round (No. 39) of the 2011 NHL Draft, Gibson set NHL career highs in games played (60), wins (31) and save percentage (.926) last season. From the All-Star break through the end of the regular season, Gibson went 14-4-2. He also had a 1.95 GAA and .937 save percentage in that span, each the best among NHL goaltenders with at least 20 starts.
