Listen, I love Leo Komarov. For so many reasons. He obviously loves being a Leaf, he's sometimes hilarious, sometimes just awesome, and recently, has been scoring an awful lot of goals for the Toronto Maple Leafs. In fact, he currently leads the team in this regard, and perhaps the coolest part about it is that he's doing it all for $2.95M per season.
On a Leafs team starved for goals and good news (and not exactly in the greatest cap position of all time), why on earth would you trade a guy like that? Two words: asset management.
At this point, any players older than, say, James van Riemsdyk will be well past their prime by the time that the Leafs are good enough to compete, so why not sell high on anything not nailed down by a NTC or NMC? Komarov currently boasts a 22.0 Sh% which is certain to regress, and he will also be 29 in about a month, and so definitely can be considered a player on the wrong side of the aging curve - especially given the physical nature of his play. His contract status (locked up for two more years at a reasonable rate) makes him eminently movable, so why not?
The thing is, Komarov's recent success is not entirely without substance. As his HERO chart shows, he does indeed help to suppress shots against, something the Leafs have struggled with for the better part of a decade. Moreover, his CF Rel TM is ranked as a second-line talent, which is non-negligible, especially given Komarov's reasonable salary.
If there is one important caveat to the above possession stats, it's the fact that he begins an inordinate amount of his shifts in the offensive zone:

Another aspect of Komarov's value is his ability to mentor younger players. Young and talented teams can indeed benefit from the presence of a veteran, and the fact that Komarov can speak seven different languages can only help teammates who struggle with language/cultural barriers in their time in Toronto. Furthermore, Komarov's work ethic, on-ice defensive commitment, and general love of Toronto can only set a good example for other players, and encourage a positive organizational culture.
So overall, although Komarov provides great salary cap value to the Leafs in terms of his scoring, possession numbers, and (probably) leadership, the Leafs need to consider the other, uglier side to this same coin: Komarov is valuable to other teams for all of these reasons, but the Leafs can maximize the value he brings to this team by trading him before his shooting percentage falls, before a shift in zone starts affect his possession stats, before he gets too old, and before his contract runs out and loses controlled value.
The fun part for Leafs fans if Komarov were to be traded is that the team could probably get great value for him. His scoring is above-average, and although his advanced stats aren't flawless, they look good, and he has as fair bit to offer in terms of intangible skills, both on and off the ice. Could the team get a first round pick for him? If he continues his current level of play, it's almost a given they'd get more.
I wouldn't be happy to see Komarov go to another team at all. The tough thing is, it's probably the right move for the Leafs at this stage in their rebuild.
