Asked about the potential for an offer sheet being given to Marner, Dubas said his intention is to keep the forward but that it would be contingent on the details and other pending free agents.
"We're at the point now -- we can speak openly about it -- it would really depend on any of the players," Dubas said. "It's not just one guy. We've got a number of them."
He mentioned forwards Kasperi Kapanen and Andreas Johnsson, who each is a pending restricted free agent like Marner.
"If there were an offer sheet, we'd look at what they are and what the compensation is for our team and make the decision based off that," Dubas said. "They're all very important players for us, so it's our intention they're here for as long as we can possibly keep them, but if the dollar amount doesn't make sense in terms of our internal economics in the marketplace and the compensation and such, it's going to be a decision on our end as to what we do. I wouldn't know one (way) or another without knowing where those are going to land, if they happen."
Compensation to the team losing a player to an offer sheet escalates from no compensation for a contract worth $1.4 million or less per season, to four first-round draft picks for a contract worth more than $10.5 million per season.
Marner, selected by the Maple Leafs with the No. 4 pick in the 2015 NHL Draft, led them with 94 points (26 goals, 68 assists) in 82 games this season. Kapanen had 44 points (20 goals, 24 assists) in 78 games, and Johnsson had 43 points (20 goals, 23 assists) in 73 games.
Dubas said he expects to meet with Marner's agent, Darren Ferris, in the next few days. Both are here for the 2019 NHL Draft on Friday and Saturday.
"I suspect in the coming week they'll be some movement, and that's what we're hopeful for," Dubas said. "I don't sense there's any pressure. We'll continue to do what's right for our organization and roll from there."
Dubas defended Marner after being told the forward has been called greedy on social media amid reports that he is looking for a long-term contract at about $11 million per season.
"For me, Mitch Marner's reputation is beyond reproach," Dubas said. "He comes to the rink every day with the exact same attitude. Great energy. Loves hockey, loves playing in Toronto, he's a great member of the community.
"I get that these matters become complex because of the number of dollars that are in play. People hear them, whether they're factual or not, and they begin to draw certain conclusions about players and what their motives are."
