A physically engaging two-way forward, Grebenkin was no stranger to this sort of hard-nosed style in the KHL, using it to his advantage in order to succeed against older players. Grebenkin, a right winger, would most likely play in a bottom-six role in that spot, a benefit to him potentially making the club given a lack of other depth forwards and prospects in Toronto who are a natural RW.
In 67 games for the KHL champions Metallurg, Grebenkin had 19 goals and 41 points, along with 6 points in 23 games for the Russian club.
