Kane finished the tournament with zero goals and four assists in six games. He failed on a breakaway attempt against Russia during pool play and missed two penalty shots against Finland in the bronze-medal game. The U.S. was shut out its last two games and didn't medal after taking the silver in the 2010 Olympics.
"I thought Kaner had several chances and had the puck a lot," Quenneville said Sunday. "He's very dangerous. He didn't have the finish or the show that could have been there. But when Kaner has the puck as much as he does, generally good things happen.
"But goalies and goal-scoring throughout that tournament, goaltending was great and goal-scoring was tough to come by. A couple of tough ones there in the shootout and penalty shots as well. I thought Kaner played well the last few games."
Quenneville wasn't worried about Kane failing to produce when he returned to the Blackhawks. He expected Kane to pick up where he left off. He is fifth in the NHL with 63 points, which includes 27 goals and 36 assists.
"He's having a great year," Quenneville said. "His consistency this year has been in the right place, game in, game out he's a threat. You watch him over there, has the puck a lot. Has the puck a lot here and does a lot of good things."
