"He's got a history of scoring at the collegiate level. He's got pace to his game. Those are two things right off the bat," Cassidy said of why Bjork was a fit in that position. "Getting to know him as a person, I think he's receptive to those types of players and we're hoping he can keep his identity as a player that he's developed so far in his young career and do the things he needs to do to be successful, but also work with those guys and respect what they're trying to do."
Bjork, who signed with the Bruins in May after a stellar junior campaign at Notre Dame, is among a large crop of young players competing for spots up front this camp. And gaining experience alongside the likes of Bergeron and Marchand will no doubt help his cause.
"It's really cool to practice with those players. I learned a lot," said the 21-year-old, who was drafted in the fifth round in 2014. "It's crazy to think about the people you're skating next to. You sort of have to not think about them and just focus on playing your game and doing the best you can and doing the little things right. I just tried to not overthink it out there."
The trio's time together on Friday was brief, as most of the work was done in pairs, but the limited exposure to two of the game's best still provided plenty of valuable material.
"You saw out there today how Bergeron and Marchand, every little puck battle they're competing 100 percent," said Bjork. "Doing all the little things right really adds up. Trying to copy that and do that myself.
"They talk a lot on the ice and tell me where they want me and little things like that, which is really helpful. They've done it before and they made practice today very easy."
Marchand, who said he's been impressed by Bjork's skill and skating ability, felt it was important to make the youngster feel comfortable during his first professional training camp session.
"For me, when I came in, I was always worried about making the other guys happy and giving them the puck and almost giving them a little too much respect. It can take away from your game a little bit," said Marchand. "I think the biggest thing is you just have to go through and play and be comfortable to talk to guys.
"It becomes on us on as well, we really have to try to make them comfortable and do as much as we can. He seems like a really levelheaded kid and a really nice kid. We'll work hard and we'll work together and talk and hopefully we connect."
