SAN JOSE >> The next week will likely be the most crucial time of the year for San Jose Sharks general manager Mike Grier.

Besides concluding preparations for this week’s NHL Draft in Las Vegas, where the Sharks will have the No. 1 overall selection and four picks in the top 42, Grier must get ready for free agency and finalize decisions on next season’s roster.

It’s a transformative time, and the Sharks figure to be a somewhat different-looking team from the one that concluded this past season with a league-worst 19-54-9 record.

“It’s a chance to build your team up again,” Grier said Monday in a conference call with reporters. “It’s a fun time of the year. Obviously, having the first overall pick is a big moment for the organization.”

Grier could barely contain his enthusiasm for presumptive No. 1 overall pick Macklin Celebrini, who has all the makings of a future cornerstone player for the Sharks.

“He’s a driven kid. He’s an Alpha, kind of everything you expect and have experienced from other No. 1 picks,” Grier said. “He has all that stuff (plus) the belief in himself and the will and the want to get better and work on his craft. He’s an impressive kid.”

Here are other takeaways from Grier’s availability:

PERSONNEL CHANGES >> Grier said he will not issue a qualifying offer to defenseman Calen Addison, a restricted free agent, and will likely allow pending UFAs such as forward/defenseman Jacob MacDonald, forward Justin Bailey, and goalie Devin Cooley to go to market on July 1.

Addison’s departure was not necessarily unexpected. He had just 12 points in 60 games this season and averaged just over 17 minutes of ice time per game. He was also a healthy scratch on a few occasions.

But the Sharks already have six defensemen signed for next season, with Henry Thrun and Ty Emberson both restricted free agents the Sharks want back. Plus, the Sharks have Shakir Mukhamadullin on the verge of becoming a full-time NHL player.

“We gave him an opportunity, and where we are right now, we have some other guys ahead of him,” Grier said of the 24-year-old Addison. “We need to probably take a step up as far as someone who could run the power play. Calen did fine here, and I wish him the best. But you have to make some decisions. You only have so many guys and so many roster spots.”

A report indicated the Sharks were interested in acquiring forward Cam Atkinson from the Philadelphia Flyers, but Grier said there was “nothing to that rumor. He’s not someone we’re talking about.”

The NHL’s buyout window opens later this week, but Grier said he is not planning to buy out anyone’s contract at this time.

GOODROW SITUATION >> Grier expects newly acquired forward Barclay Goodrow to attend the team’s training camp in September, even though he said the veteran is probably still processing his abrupt and unceremonious departure from the New York Rangers last week.

“When you’re an athlete, even though it’s a job and a business, there’s definitely an emotional element to it,” Grier said Monday in a pre-draft conference call with reporters. “And I think (Goodrow) and his family have gone over the rawness of the situation, and I think the disappointment of the situation.

“But I think he’s someone who will be excited to get back to San Jose and be a part of the group.”

In a salary cap-related move, Goodrow was placed on waivers by the Rangers last Tuesday, something he reportedly did not become aware of until shortly before it happened. The following day, Goodrow was claimed by the Sharks, one of the 15 teams he had on his no-trade list.

Being a part of a rebuild will be an adjustment for Goodrow, who has been on playoff teams for seven consecutive seasons.

COUTURE’S HEALTH >> Grier spoke with Logan Couture last week and said the Sharks’ captain “feels pretty good, so I think he’s optimistic about everything. So we’ll just see how the rest of the summer goes and how he keeps training.”

Couture missed all but six games last season with a sometimes debilitating condition called osteitis pubis, raising questions about whether he would be available for the start of training camp in September.

Grier said Couture’s plan is to begin skating after he returns to San Jose in July, “and we’ll just kind of take it from there.” Grier emphasized last week that he has no interest in trading Couture.

COACHING SITUATION >> New coach Ryan Warsofsky is still in the process of finalizing his staff, Grier said, as it remains unclear as to whether assistants Scott Gordon, Brian Wiseman, Thomas Speer, and Nick Gialdini will be back for a third season in San Jose. Those coaches are free to seek employment elsewhere.

“Hopefully, once we get to (development camp in early July), we’ll have one or two pieces of the staff in place,” Grier said.

The Sharks have still not hired a head athletic trainer to replace Ray Tufts, who was let go, along with David Quinn as coach, on April 24. Grier said Mike Potenza, who has been hired as the team’s director of high performance, will have some input on who that person will be.
