Provided the Pens stay at 46, there should still be some interesting options left.
Denis Guryanov would definitely be my number one choice. Honestly, he should be a first rounder. However, I see that he is not ranked as highly by everyone, so there may be a chance he is there at 46. He is big, skates well, and has an awesome shot.
Zach Senyshyn is second on my list. Like Guryanov, he is also a big winger with plus skating. However, while Guryanov scores with both his shot and by driving to the net, much of Senyshyn's game is based on flying down the wing and heading straight for the net.
Mitchell Stephens is another interesting player. While he plays center, and could probably play there in the NHL, I agree with those who think he can transition to wing pretty well. He is a dynamite skater, and, while not a big player like the previous 2 at just 6' and around 190 lbs, he might be more physical than them. I dont think his offensive game is at the same level as Guryanov's and Senyshyn's, but he is a puck hound that still has some offensive prowess. Also, he gets rave reviews for his character.
Jack Roslovic is another center that might convert to wing in the NHL. Good size and skating ability. He is more of a passer than a shooter, which could be a good thing, as it might force Crosby and Malkin to shoot more.
Blake Speers is also interesting. Like the other players on this list, he has plus skating ability, but, like Stephens, he lacks size, though he will stick his nose in the dirty areas to make plays. Speers looks to pass more than he does to shoot, but his shot is good enough to keep goalies honest, especially if he would use it more.
Well, those are the top 5 wingers on my board around 46. Interestingly, they are all right-handed.
