TAMPA — No one in Tampa Bay was surprised to see Steve Yzerman leave the Lightning for Detroit. The biggest question was who would go with him.We now have an answer. Pat Verbeek is joining Yzerman in Detroit, the city where both played and still live. The other four members of the hockey operations executive staff are staying.Losing two thirds of the management triumvirate that built the Lightning is a hit, but Tampa Bay isn’t starting a fresh with a new management group.Al Murray (director of amateur scouting), Stacy Roest (director of player development) and Jamie Pushor (director of professional scouting) have all been promoted. They will each be an assistant general manager, overseeing the same divisions.Additionally, the Lightning hired Matheiu Darche as director of hockey operations.“It wasn’t as much about keeping as many people as possible, as it was these three people,” Julien BriseBois said after the announcement Monday morning.“All of them contributed to building a competitive organization over the last eight, nine years. It gives me a lot of comfort to know I can keep counting on them.”That some would follow Yzerman seemed inevitable – that’s typically how these things go – but the Lightning maintains mostly the same management core.Julien BriseBois had been with the team almost as long as Yzerman when he took over as general manager this year. Murray has been with the organization for 10 years, Pushor for eight and Roest for seven.The Lightning’s strength has been its development program – see: Erik Černák, Anthony Cirelli and Mathieu Joseph this year. Maintaining key pieces of that group is important for this franchise.Murray is responsible for the Lightning’s draft preparation, highlighted by some of the high-caliber picks outside of the first round. Murray was largely behind the Lightning grabbing Nikita Kucherov in the second round and Brayden Point and Anthony Cirelli in the third, for example.Roest has been working with the prospects once the prospects are in the system extensively already. BriseBois called him the Crunch’s “de facto assistant general manager,” saying he created the job description of director of player development, and now Roest takes over as general manager.Much of the Lightning’s management and coaching staffs came up through the AHL. The organization highly emphasizes the development league.“What happens in Syracuse is of paramount importance to our success going forward,” BriseBois said.He’ll still be very much involved with what happens in the AHL, but he’ll be in Syracuse less often going forward. Promoting three assistant general managers and hiring a director of hockey operations gives BriseBois some more flexibility with his own time.“A lot of it is time to think,” said BriseBois. “The time you’re spent on doing stuff is time away from thinking.”He’ll have more time for conversations with scouts, with agents, with general managers. Those are all conversations that inform the organizations’ view on where it stands in the league overall.As assistant general managers, each of Murray, Pushor and Roest will have more involvement in the organization overall than he did previously. For example, Murray hasn’t been part of the year-end meetings to discuss potential trades and free agent signings. He was last week.Pushor’s title changes from director of professional scouting to director of player personnel, a role he shared with Verbeek this season. It’s still overseeing the players in the other 30 organizations. BriseBois said the Lightning might bring someone in or promote someone to help with that.Darche is the only new hire at this point, but he’s known within the organization. Pushor and assistant coach Jeff Halpern played with Darche and assistant coach Todd Richards coached him. BriseBois signed him to the Hamilton Bulldogs when he worked in the Canadiens’ organization.He was involved in negotiating the AHL and NHL’s collective bargaining agreements, on the players association sides, so has an in-depth knowledge of both, which will be helpful.Some wondered if BriseBois might bring in more new people with an opportunity to do his own hiring. Even internally, someone asked if that’s what he’d like to do.“I told him, ‘you are the people I’ve worked with in the past and that I like,’ ” BriseBois said.
