The Scotiabank NHL Centennial Classic between the Maple Leafs and Red Wings took place Jan. 1, 2017 and was won by Toronto 5-4 when forward Auston Matthews scored at 3:40 of overtime.
"That one was awesome," Rielly said. "Being at home, doing it in front of our fans, not having to travel, having my family there and, of course, the outcome."
After not getting a point in Ann Arbor, Rielly had an assist at BMO Field. Fourteen months later he would be held off the scoresheet in the Maple Leafs third NHL outdoor game, a 5-2 loss to the Washington Capitals in a 2018 Coors Light NHL Stadium Series game at Navy-Marine Corps Memorial Stadium, home of the United States Naval Academy in Annapolis, Maryland, on March 3, 2018.
"That one was cool just because what that place is and what it represents," Rielly said. "And it was great to be there a couple of days early and learn about the history and such. The result, well, that wasn't so good."
Rielly hopes the Maple Leafs will fare better on Sunday after losing to the Sabres 5-1 in Toronto on March 2.
"We know how good they are," he said. "Today is about having fun and enjoying the experience. On Sunday, it's all business. Whether it's cold and windy like it's supposed to be, you just have to move the puck quickly and deal with it. It's the same conditions with both teams."
And once the final horn sounds, win or lose, the memory of yet another special game in the elements will be added to his personal file.
"I have bottles of wine from the Michigan game with the logos of the two teams on them," Rielly said. "My dad still wears Winter Classic parkas in the winter."
He broke into a wide grin.
"These are the little things that you collect over time that, you know, mean more than just another game. And Sunday will bring more of them."
Including a cherished memory between father and son.
