The Senators started Phaneuf and the puck rolled to him off the opening faceoff. He bobbled it and the puck was scooped by Toronto forward Brooks Laich, who drove hard to the net and took a backhand that was stopped by Ottawa goaltender Andrew Hammond.
"Look at the first shift and wow, I thought it was going to be a long night," Phaneuf said. "I bobbled the puck off the start, give them that chance to [score]. I didn't feel my best to start and then after the tribute obviously I was emotional, I kind of dialed in. I said I've got to be better than I was for this team, they deserve better than the way I started."
The video during a first-period stoppage showed highlights of Phaneuf's time with the Maple Leafs, and he had tears in his eyes sitting on the Senators bench.
"I'm an emotional guy," Phaneuf said. "I said that this morning. I wasn't lying, was I?"
