Athanasiou put Detroit ahead 2-1 at 6:15 of the third period, eight seconds after Red Wings defenseman Danny DeKeyser blocked Tony DeAngelo's shot at an open net.
"That's the biggest play of the game right there," Blashill said. "Jimmy makes a huge save and then Danny throws himself in front of the rebound and we go down and score. That's how this league works; almost every game is close, and one play like that can make the difference."
After the goal, Athanasiou pointed to Ted Lindsay's No. 7 jersey in the rafters. Lindsay, a Hockey Hall of Famer and four-time Stanley Cup champion with the Red Wings, died Monday at the age of 93. He was honored before and during the game.
"I just wanted to pay a little thank-you to Ted," he said. "I thought tonight was a good tribute to him."
Buchnevich made it 2-2 at 14:29, beating Detroit defenseman Niklas Kronwall down the middle of the ice and flipping a shot in off Howard's shoulder after a long pass by Brendan Lemieux.
"I saw he had a step on his man, so I tried to get the puck in front of him," Lemieux said. "I figured, if nothing else, he could prevent icing, but he's got so much skill that he made a play and tied the game."
