I really don't think the Avs need another winger, if they get a legit 2C:
Lehky - Mack - Drouin*
Nuke - 2C - Mikko
Wood - Colton - LOC*
Cogs - Olofsson - Kiviranta
Keep in mind there's a decent chance Kovalenko ends up taking the 3rd line RW slot and bumping LOC down. And then at least as of right now Drouin loses his spot to Landy. Which then gives you Kiviranta as injury replacement #1 in the bottom 6, Drouin as injury replacement #1 in the Top 6.
Also keep in mind we may not even move RyJo in a trade this year so then he could be another extra body option as well.
The 2C has absolutely got to be solved, but I really think if you fix that with an actual solution(Like JEE, Lindholm, Nelson, Zegras, etc) and not another bandaid, you've got a plenty deep forward group that can win it all.
But right now the 2C hole is killing us because it has literally everyone else on the team playing roles and minutes they simply aren't capable of sustaining or doing well in.
Obviously we won't know for sure what the situation is with Landy until much closer to the deadline but I think until we hear otherwise they probably should operate under the assumption that he'll be back and thus focus all of our attention on the 2C slot.
