This is the only way a Habs prospect can win a poll, eh?
On a more serious note, I would say that Perezhogin is likely to have the better career. He may be on the small side, but I see great upside for him. I think he'll be in all likeliness a legitimate top 6 forward. His downside is probably a third line speedster who's defensively responsible and capable of contributing to the offense, a bit like Niko Kapanen in Dallas. As for Kostitsyn, he's got superstar potential all over him. That will depend on many factors, including his ability to adapt to the North American style of play (more physical and more focused on defense) and ice size. He really is the typical boom or bust prospect. If he can't translate his offensive game at the NHL level, I really don't see him become a bottom line player. He still has a lot to learn in order to be able to make an impact in the NHL, but skill wise, he's already up there. The problem is: it takes more than talent to play in the NHL these days.
That's why I'd rank Perezhogin ahead of Kostitsyn, for now. You have to consider though that 2 years makes one heck of a difference in a young player's career. Kostitsyn is looking just as lost as Perezhogin did when he first played for the Bulldogs. Let's wait and see now if Kostitsyn will be able to catch fire in the 2nd half just like Perezhogin in 2003-04. I'm not really expecting that from him though, considering that he's still 19, whereas Perezhogin was 20 in his rookie season.
