I would put them as 1a and 1b right now as far as our forward prospects go. I've been extremely high on Athanasiou for a couple years now, and there's no question that he has had the much better start to his pro career. Mantha, I think will be a great player as well, he's just taking longer to adapt to the pro game. I think they will be 1 and 2 in scoring for the Griffins next season and I wouldn't be at all surprised if they are both top 5 in the league.
The thing for me is, I think they are both very different players but both will be just as effective in their own way, but I think Mantha is slightly overrated, while Anthanasiou is slightly underrated league wide and even by some Wings fans... All the talk has been about Mantha and Larkin, but I am just as high on Athanasiou as either of those two for sure.
