Can't agree on Kobasew. As I said, I like him a lot, but I'm not a fan of his finishing ability. It starts back in the WJC a few years back when he was on a line with Jason Spezza. And Kobasew's inability to finish the chances Spezza gave him, often on a nice silver platter, was quite dissapointing. He's a great skater, with loads of energy and some slick, learned moves, but I don't think he has good goal scoring instincts. A 30 goal scorer in today's NHL is a pretty darn good player. Patrick Marleau for example, has yet to score 30 goals in the NHL. He's put up 28, and is a 30 goal calibre player, he just hastn' netted two more goals to make it official.
The other problem with Kobasew is that he can get knocked off the puck too easily. If he bulks up a few pounds, I think he'll be a Chad Kilger type of player. I don't see Kobasew as a big goal scorer. Saprykin is the young Flame who I see scoring a lot of goals in the NHL. But I just don't think Kobasew has what it takes to be a first line player in the NHL.
As for Tambellini, I'd want to see more of him to be more adamant in my questioning his upside. He's a great skater no doubt. And I think he's already more advanced in his checking game than Bure ever was (although I'd still take Fritsche in this regard). But I guess it's the same as Kobasew. Something about them makes me question their goal scoring ability. Some players like Kobasew can put up big numbers right away in college because it's a game that plays into the hands of the smaller, speedy players. That to me explains why guys like Tambellini and Kobasew can walk in and score immediately and in Tambellini's case, why he may have struggled in his second year a bit. He didn't have to adapt to the college game off the bat because he's fast and has a great shot, so he hit the ground running. Now teams have begun adapting to him, and he struggles a bit.
That's just my feeling though. I have never seen Tambellini playing in college, so if you have, you're probably more qualified to make that type of assessment. I'm just a sceptic though.
