To be successful the Leafs need Hyman and more players of his ilk and style of play.
However with a flat cap locked at $81.5 mil for the next 3 years the current plan on the table Leafs will have little cap space to work with and lots of uncertainty.
I think Dubas is going to work on this next season ahead first, then count the cap pennies he has left after that dust settles, before worrying about the following year where Andersen becomes a UFA and Reilly enters his last year that also will need addressing.
If Dubas were to deal away a big cap heavy piece like Marner for help on defense, then there would be more cap room to retain a player like Hyman going forward, who is currently on a cap friendly deal of $2.25 mil and delivering +20 goals and a world of intangibles that Leafs overall roster has so little of what he brings to the table.
More than likely however, if Leafs don't find success this season, we will likely have new management in place, and then Hyman will then fall to them to decide his fate and his next contract.
