Quoting: Truebeliever
The knock on Stanley is mainly his shot. It's not big league. But of all the failings, that one more than any can be taught. Look at Gorges as an example. The guy has good hockey sense and positioning, is huge, pretty coordinated and, for his size, a really good skater. He will be an NHLer, though will he live up to first-round status, that remains to be seen.
Speaking from experience, big/strong kids often struggle with their shots because, growing up, they don't want break the shafts of their $300 sticks (dad's get mad). That's one of the reasons that, for some, the shot only starts to develop at junior when you can eat through sticks. Regardless, getting muscle behind a shot is the easiest part of hockey to teach. He might never be Weber, but, as you said, Gorges is an example of a guy with not a great shot who learned to be good enough and has had about 800 games to show for it.
On the Borgstrom trade, I am not sure you can count on him to be the #1 C ever, let alone next year. He's still just a sophomore at Denver. Even if he signs, he'll take a bit of time in Laval to develop.
