These guys follow these kids for a few years, last year Friedman reported that the Rangers has been following Chytil since he was 14/15. If any of these scouts like a guy, they get other people to get some eyes on them. The consensus could be a decent way to sketch out ranges for where players are going to go, but teams scouts get way more specifics about these kids.
In the case of Kravtsov, they definitely did a lot of homework on him, Gordie and Drury both went over to watch him play a bunch even before his playoffs. The playoffs are what had him rise later in the year, but playing 9 minutes a night in a checking role on a non-powerhouse KHL team isn’t exactly the best way for a prospect to get noticed, but during the Olympics when he played in the VHL, he dominated. He doesn’t have Wahlstrom’s numbers, but he’s absolutely in the same tier with Wahlstrom and he’s an even more well rounded offensive player.
