It’s no secret that the Leafs need to fill the position of right winger in the absence of Mitch Marner. The Matthews, Knies first line is still incomplete, and no one has won the spot just yet.
There are two clear options for who can take the position, and one that may be a rogue opinion. I think Domi, Macceli and Joshua are top contenders.
Max Domi
Firstly, Domi has proven success on this line, especially working with Knies. In addition to points gained while all three players are out together. Knies has developed a physical game, specifically last season, where we saw him use his size and weight in the boards and to shut down opposing players.
