There have been highly touted busts. What makes you think Demidov won't bust, or just be a good offensive player without being a star?
It is not impossible, and all of our high draft picks in the decade prior to Slafkovsky have busted.
My concerns regarding Demidov are less than those that I had with Kotkaniemi because the former was not an unexpected reach based in part on position and need, but until they hit NHL ice, every prospect is worthy of cautious optimism.
With Demidov, fundamentals of his game that should translate well to the NHL - IQ, Vision, shot - are more refined, and there are no injury uncertainties or, as far as we and Bobrov, who has been familiar with him for years, toxic family influences. Those alone separate him from Galchenyuk and Kotkaniemi.
