Last season, Arizona goaltenders had a 2.73 goals against average and .912 save percentage, which ranked them in the upper half of the league in both categories.
Tippett said the team made too many errors with the puck and had too little discipline in the game.
"The goaltending's gotta get better," Tippett said to the Arizona Republic. "If the goaltending doesn't get better, then we're going to struggle like that."
Arizona goalie Mike Smith only stopped 21 of the 27 shots he faced.
"My average games are better than most I think, but that wasn't close," he said. "That wasn't where it needs to be, and I'll take responsibility for that."
