As long as you stay away from the pitfall of thinking "We could have had this player in the 3rd round because we got Buchnevich in the 3rd round", I think it's okay to find the comparison discouraging.
Expecting more from a top-10 pick is normal. But at the same time I feel fans in general (across different fanbases) have flawed expectations of a player drafted in the 7-12 range. This isn't the NFL or NBA where you draft kids out of college at age 21-22. These are 18 year old kids and after the can't-miss prospects at the top (usually no more than 3) the drop off is significant.
Players drafted in the same range as Kravtsov include Couture, Hartnell, Kopitar, Granlund, Carter and Couturier but on the other end of the spectrum you have guys like Olesz, Picard, Hammill, Skille, Sheppard and Glennie. A pick in the latter half of the top-10 is very much hit-or-miss but we tend to focus on the successful picks rather than managing our expectations. It's what fans do. Can't blame them. But it's important to stay grounded when a player has a good season early on. A lesson I need to teach myself from time to time as well
