And I wouldn't be surprised in the least if Joshua got Mikheyev'd within the next two seasons.
Just turned 28 year old, who had a career season, while shooting 20% and often finding himself on the right end of a lot of chaos-y/opportunistic plays. Often that lightning doesn't strike twice, especially once those guys get a little job security. Jeannot's the current poster boy for this.
As said, I don't see a lot of structure to Joshua's game. In my eyes, there's not a lot of difference between him and Foegele. Another guy who relies on a chaos-driven, opportunistic game, and one I would steer the hell away from for anything north of 2.5mil,
Also your 3rd paragraph doesn't make much sense. You say they should be on the lookout for these players, but Kostin's not a good example? At the end of his 24YO season (where Klim is now) Joshua was a minor league and had all of 12 games NHL games to his name, and was still over a year away from making a proper impact at the NHL level. If you were asking me for a list of guys in their mid-20s that could grow into an energy 3rd liner-type, he'd be near the top of the list.
