"We've had discussions with both camps already," Dubas said of Marner and Matthews. "We'll continue to do that. We want to avoid a situation where not all our players are here at training camp. We're happy to have a solution [with Nylander], but this is not the preferred timing of the solution.
"That's the plan, to avoid it with the others. It's our full plan to have everybody available for the first day of training camp."
In the short term, Dubas has helped give coach Mike Babcock arguably the strongest group of top-nine forwards in the NHL by signing Tavares and keeping Nylander.
"To get where you want to go in this League, you need depth," Babcock said. "You can't have just one dominant line and expect to have success in the playoffs. The [Stanley Cup Playoffs] are a grind and you need different guys stepping up every day."
That potential is there for the Maple Leafs, who have not won the Stanley Cup since 1967.
Consider this: seven of their top nine forwards are first-round draft picks; Tavares (No. 1, 2009, Islanders), Matthews (No. 1, 2016, Maple Leafs), Patrick Marleau (No. 2, 1997, Sharks), Marner (No. 4, 2015, Maple Leafs), Nazem Kadri (No. 7, 2009, Maple Leafs), Nylander (No. 8, 2014, Maple Leafs) and Kasperi Kapanen (No. 22, 2014, Pittsburgh Penguins).
Kadri scored the winning goal in Toronto's 5-3 victory at the Minnesota Wild on Saturday. In each of the previous two seasons, he scored 32 goals. Few, if any, NHL teams can get such production from their third-line center. Kadri, who has 16 points (eight goals, eight assists), plays behind Matthews and Tavares.
Where Nylander fits in the lineup remains to be seen. He's scheduled to join the Maple Leafs for practice Monday, which will provide an initial hint of the line combinations Babcock envisions.
Conventional thinking suggests Nylander will be reunited with Matthews. They showed good chemistry as linemates last season when Nylander finished third in team scoring with 61 points (20 goals, 41 assists), behind Marner (69 points) and Matthews (63). Marleau, 39, or Kapanen, 22, are the likely choices to play the other wing.
The Maple Leafs are on an 11-3-0 run without Nylander, outscoring opponents 55-31. His addition only makes them better in a season where their Stanley Cup aspirations are legitimate.
That's why getting him signed was such a key.
Their salary cap structure will be significantly altered next season, given the new contracts Marner and Matthews will require. There's also the dilemma of what to do about 28-year-old defenseman Jake Gardiner, who can become an unrestricted free agent July 1.
As a result, players, management and fans all understand that there is a window of opportunity to win now. This season. Thanks to Dubas helping to secure key pieces in place like Tavares and Nylander during his short time as GM, the dream of becoming a serious Stanley Cup contender has become reality.
