For Toronto Maple Leafs forward Nazem Kadri, it admittedly was one of the worst moments of his NHL career.

For Boston Bruins center Patrice Bergeron, it was among the best of his.

When the Maple Leafs visit the Bruins in Game 1 of the Eastern Conference First Round on Thursday (7 p.m. ET; NBCSN, CBC, TVAS), it will be the teams' first playoff game against each other since Boston eliminated Toronto in seven games in the first round in 2013.

But the Bruins did more than win the series. They made history and broke the Maple Leafs' hearts. Down by three goals 5:29 into the third period of Game 7, Boston rallied for a 5-4 overtime win, becoming the first NHL team to win Game 7 after trailing by three in the third.

"Lesson learned," Kadri said. "You take what happened and understand how to better handle that situation if it comes up again.

"We have young guys on this team who were still in school back then. This is a different team."
