Tyler Seguin was a 12-year-old Toronto Maple Leafs fan the last time the Original Six franchise qualified for the postseason, so he knows exactly just how crazy it’s going to be in Toronto over the next couple weeks.

“I already looked at my phone and had more text messages than usual,” he said following Boston’s 4-2 loss to the Ottawa Senators on Sunday night that locked the Bruins into a first round playoff series with the Leafs. “Definitely the town is going to be excited, but I think we will be as well.

“Any time you’re in the playoffs, the atmosphere is pretty great. I’m sure Toronto is going to be good as well. I guess I’ll turn my phone off for the playoffs. I’m sure there are going to be a lot of storylines, so I’m definitely excited to get started.”

The 21-year-old forward will be expected to be one of the vital pieces for the Black and Gold after finishing with 16 goals and 32 points while playing all 48 regular season games for Boston. He’s teamed with Brad Marchand and Patrice Bergeron to give the Bruins their most consistent forward line in a shortened season that’s been anything but consistent and will be looking forward to starting from scratch in the postseason.

“I think we’re starting fresh, [so there’s] definitely a sigh of relief, I guess,” said Seguin. “I think we’re going to move on [from the regular season] and start getting ready. It’s been a very up-and-down season for me, and I think for us a unit.

“Everybody here is excited it’s a fresh, new start. We know we’re playing a good game right now. Right now it’s just about scoring more goals. I think the last few games if we had one more here and there — and even in the first and second period, not just last minute — we’d be good.”
