For starters, I can't even say if KHL is the undisputed second best league in the world anymore this season now that most of the foreign talent has bolted. During the past decade approximately 25% of the players have been foreigners while this season the number has gone down to 10%, not to mention all the foreign teams and coaches quitting. This has undeniably affected the level of play in the league.
And even before this season there were some really questionable teams and games in KHL. I remember when Eeli Tolvanen broke the underage scoring record in the KHL just to face major difficulties in North America, even with NA junior background. Another Finn, Niko Ojamäki, scored 29 goals in the KHL last season during a shortened season, but has faced some problems coming back to Finland this season. He has publicly talked about how the game in KHL was less tactical and there was more room to maneuver on the ice.
Sometimes things just click and sometimes they don't work out. The sample size of Michkov play in the KHL is too small to make an argument in any direction, and even with a bigger sample size the stats don't always tell the whole truth.
As I already said, Michkov might be a great prospect and he might make a great career, but that's not a reason to downplay Bedard's talent at all. Based on watching Bedard's play for the last couple of years and watching KHL actively for several years (during which the league was arguably at a better level than this season, mind you) there is just no doubt in my mind Bedard could cut it in KHL right now, and most probably do better points-wise than Michkov is doing. Arguing the opposite seems to me downright silly.
