Bozak has played seven playoff games at TD Garden, his teams going 3-4, including 1-3 last year with a 7-4 loss in Game 7.
An upper-body injury prevented him from playing Games 6 and 7 of the 2013 series, meaning he wasn't here when the Bruins came back from down 4-1 to win Game 7 in overtime, 5-4.
"Obviously playing in Toronto, they're in the division and a team you have to play through," Bozak said at Stanley Cup Final Media Day on Sunday. "It's nice for me to have the experience of playing in this building in the playoffs in that atmosphere. I think that will help me a little bit."
Bozak said he has heard from former Maple Leafs teammates, all wishing him good luck. It wouldn't have been surprising if one or two included a motivational message along the lines of "Beat those bums," or something more profane, but Bozak said that hasn't happened yet.
"They're just happy for me being here and wish me all the best," Bozak said.
That Bozak is here, still playing this season, brings to light some of his foreshadowing from when he signed his three-year, $15 million contract with the Blues.
He wrote in an article on The Player's Tribune that although he's proud of his accomplishments in Toronto, the regret is that he never won the Stanley Cup.
"I want to win a Cup. So [darn] bad," Bozak wrote. "That's why I signed in St. Louis. There's your headline. Print it."
Here's his chance and once again the Bruins are standing in his way.
Tough to predict that one.
"It's surreal to have this opportunity," Bozak said. "It's something you dream of your whole life, so no matter who we're playing, I'd feel the same way."
