The games are done for the top draft prospects; there is no hockey left to be played. A few players in the top 10 played until the last possible moment, making a lasting impression on scouts and executives at the Memorial Cup. With the combine taking place this week in Buffalo, New York, players will undergo physical testing and a rigorous interview process with interested teams. The combine allows teams to ask out-of-the-box questions, get a feel for the personalities of the players and, in some cases, understand the significance of injuries.

There is room for movement on the draft board because combine testing does impact model outputs. Furthermore, this list weighs scouting as 40% of the evaluation. The final ranking, which will be published June 23, will weigh scouting, projection, off-ice assessments and industry intel to varying degrees, which may see some players move up or down.

There are five parts of this set of rankings:

• The rank, which accounts for attributed value based on projection, the confidence of the projection and scouting.

• The NHL projection weighs the projection formula at 70% and scouting at 30%, and represents the most likely outcome for that player. The final edition of the rankings will include the player’s NHL ceiling.

• The NHL floor uses the same formula and represents the worst outcome, above 10% probability of occurring. If a player has a 4% chance of never playing NHL games and an 11% chance of becoming a fourth-line winger or No. 7 defenseman, then those projections will be used for NHL floor. For some players in the draft, the floor is outside of the NHL, perhaps the AHL or KHL.

• Projection confidence is based solely on the projection formula and forms two parts: confidence and volatility. The confidence has four tiers: High, fair, medium and low. This represents that confidence the model has that the player will reach the NHL projection for 200 or more NHL games. The level of confidence impacts the value of the player and, therefore, their rank. High confidence is above 80%, fair is 60% to 79%, medium is 35% to 59% and low is below 35%. The volatility has four categories: Low, slight, medium and high. Volatility relates to the range of outcomes a player has in their career. A player with a low volatility means there is a smaller range of outcomes for the NHL career, whether that is a No. 1 defenseman to top-pair defenseman, or third-line center to bottom-six forward. A player with high volatility has a wide range of outcomes, with relatively even distributions over the NHL projection. It could be related to a number of factors: the league they play in, their scoring if they changed leagues, injuries or a significant uptick/downturn in play. Many of these players are considered “raw” in their development curve.

• Strengths are each player’s standout abilities.

“Boom or bust” is an all-encompassing phrase with confidence and volatility. It means the player either hits their NHL projection or is unlikely to play 200 NHL games. The difference between a low-confidence/high-volatility projection and a boom-or-bust projection is simple: It means injuries played a role in the projection, and the sample size makes it difficult to confidently project the player’s most likely outcome; or that the league in which the player plays does not have a successful history of producing NHL players.

One other consideration is the “Russian factor,” where skilled Russians are more likely to return to Russia if they fail to hit their NHL projection.

Montreal Canadiens defenseman Lane Hutson was named the winner of the Calder Memorial Trophy on Tuesday.

The trophy is awarded annually “to the player selected as the most proficient in his first year of competition in the National Hockey League.” The award is voted on by the Professional Hockey Writers Association.

Hutson earned 165 of a possible 191 first-place votes and totaled 1,832 points, finishing well ahead of Calgary Flames goaltender Dustin Wolf (15, 1,169) and San Jose Sharks center Macklin Celebrini (11, 1,104).

The 21-year-old Hutson received the trophy at a surprise party his family had organized to celebrate his selection as a finalist.

Hutson led all rookies with 66 points, and his 60 assists tied the single-season NHL record for most by a rookie defenseman alongside Larry Murphy.

Celebrini, 18, played 70 games and scored 25 goals — second among rookies behind the Philadelphia Flyers‘ Matvei Michkov — and his 63 points tied with Michkov for second.

Wolf, 24, was 29-16-8 with a 2.64 goals-against average, .910 save percentage and three shutouts for the Flames, who selected him in the seventh round of the 2019 draft.

BOSTON — Marco Sturm got his first taste of the passionate Bruins fans when he was traded to Boston for No. 1 draft pick — and soon-to-be NHL MVP — Joe Thornton.

“I mean, it wasn’t my fault, right?” the former Bruins forward told chuckling reporters Tuesday at a news conference to introduce him as the team’s coach. “I got here, and it was difficult. I’m not going to lie. You read the paper or social media or even you go on the street, people will let you know, right?

“But also it pushes you. And I saw it in the positive way,” Sturm said. “I’ve got such good memories here. And I know the fans, as soon as they feel that there’s something good happening here, they will support you. I know that. It kind of goes the other way, too. But I don’t want to talk about that. I want to look forward.”

A three-time Olympian and first-round draft pick who played five of his 14 NHL seasons for the Bruins, Sturm led Germany to a silver medal at the 2018 Pyeongchang Olympics and spent the next six years in the Los Angeles Kings organization, the last three as head coach of its AHL affiliate.

The 46-year-old former left wing replaces Joe Sacco, who finished the season as the interim coach after Jim Montgomery was fired in November. Bruins general manager Don Sweeney said that as the team tries to rebuild after missing the playoffs for the first time since 2016 it was important to have a coach “who understands our fan base and values the same things — of being incredibly hard out each and every night.”

The Bruins marked the occasion with a news conference in their offices overlooking Causeway Street and the TD Garden. Former captain Patrice Bergeron, who assisted on Sturm’s overtime game winner in the 2010 Winter Classic at Fenway Park, was in the front row as a show of support. German chocolate cupcakes — a nod to the new coach’s heritage — were served.

Sturm said he never considered coaching while he played, but he started working with his own kids before getting the job as head coach and general manager of the German national team in 2015.

“And that’s where I really realized, ‘This is actually me,'” he said. “And that’s where I have passion. That’s where I’m good at. And then to go after that.”

He put his plans for family time on hold and spent six years living in Los Angeles, away from his wife and children.

“I was chasing my dream,” Sturm said, adding that the children, who are now 19 and 21, missed Boston since moving away. “My kids grew up there. They always wanted to come back. And here I am. Now they get their wish.”

Sturm said he wouldn’t have taken just any opening, but the Bruins presented a team that has strong goaltending in Jeremy Swayman and a solid core led by defenseman Charlie McAvoy and forward David Pastrnak that could push for the playoffs if it stays healthy. Boston also stockpiled draft picks and young talent from the midseason trade deadline purge that dealt several veterans — including Brad Marchand, the only remaining member of the Bruins’ 2011 Stanley Cup championship roster.

After posting 100-plus points in six straight non-pandemic-shortened seasons — including a Presidents’ Trophy in 2023, when they set NHL records of 65 wins and 135 points — the Bruins finished with 76 points this season; only three teams were worse.

“Every job — it doesn’t matter if you’re in Boston or not — will be a challenge. But it’s a good challenge. I love challenges,” Sturm said. “I know the expectations here. I know how it is. But as long as I’m putting my work and preparation in, I know I will be in good shape.”
