I can't see it, neither is particularly good at driving the play and that's not a knock on either but just the way they play, Radulov was the last winger we had that could still produce in the absence of a good center and I would say that Kovalev was the last one we had before he came along. Pacioretty scored so many of his goals off long bomb passes from Subban and Markov and since neither of these guys have the luxury of having either version of those two on D I highly doubt that they are able to be very successful. ( I left out Galchenyuk because in my opinion he was at his best as a center).
They certainly aren't as skilled as Radulov, but there really aren't many players as skilled as Radulov in the NHL. I will say this about them:
Lehkonen:
-He's not much of a playmaker, but he's a shot generating machine. Close to Gallagher and better than Pacioretty.
-He was really unlucky with his shot last season. Even without a lot of distributors at center or on D, he's likely to rebound somewhat.
-He probably benefits more than anyone else if Pacioretty is traded considering they occupy similar roles.
-He's strong enough defensively to get minutes regardless.
Hudon:
-He's a strong passer that needs to get more confidence, but there's a strong playmaker there.
-He was even more snake-bit than Lehkonen and I don't think he's a worse shooter than a guy like De La Rose, especially since he's been a high percentage shooter at every other level.
Honestly, if you're holding either of them to the standard of Radulov, Kovalev and Pacioretty, you'll probably be very disappointed, because those are unfair expectations. They probably aren't going to be able to take over a game or be one of the best goal scorers in the NHL.
But both those guys are good at getting shots off, have good hands and transition the puck well. They don't take over the play by themselves, but they ARE VERY good at driving the play. That's why I'm keeping an eye on them.
