It turns out the top-six winger the Sharks needed to replace Patrick Marleau was on the roster all along.
Joonas Donskoi skated on Logan Couture's line in Monday night's shootout loss to the Ducks, and was San Jose's best player. He scored the Sharks' only two goals, and tied for the team-lead among forwards with four shots on net.
Donskoi added another goal in the ninth-round shootout, but his two goals in regulation were his sixth and seventh on the season. With those goals, he surpassed his total from an injury-riddled campaign a year ago, and stands three tallies clear as San Jose's second-leading goal-scorer this season.
Due to Melker Karlsson's injury, Donskoi skated with the Sharks' leading goal-scorer, Logan Couture, and rekindled the strong chemistry the pair has shown since the Finnish winger arrived in San Jose in 2015.
Of the nine lines Couture has skated on for at least 50 minutes dating back to the beginning of the 2015-16 season, the three best in terms of puck possession have had Donskoi on his wing. Those three combinations have controlled at least 54 percent of the five-on-five shot attempts, according to Corsica Hockey.
Adding Tomas Hertl, who's already a strong possession player, to that line bodes well for an even stronger second line moving forward. With Karlsson on the wing, the line controlled only 47.7 percent of the shot attempts, per Corsica, meaning the Sharks have been routinely out-possessed with them on the ice.
That was not the case with Donskoi in Karlsson's place, as Donskoi posted positive possession numbers alongside Couture and Hertl on Monday, according to Natural Stat Trick. The results were there, as evidenced by the game's opening goal, but it's a good sign that the process was, too.
The same, frankly, can be said of Donskoi's entire season up to this point. He likely won't convert on over 18 percent of his shots all season, of course, but the Sharks have the puck more often than their opponents when he's on the ice, and should continue to generate pressure, chances, and ultimately goals, even if Donskoi's personal scoring comes down.
When Karlsson comes back, Donskoi should remain on Couture and Hertl's line. That would allow the former to slide into a role better-suited to his game, and the latter to bolster San Jose's top-six forward group.
Donskoi's earned an extended look in that spot thanks to his resurgence, and subsequent emergence, this season. Thanks to him, replacing Marleau's production suddenly seems much less daunting.
