I think it's fair to say that, for the most part, the talent on KHL teams is not NHL level.
I would KHL teams consider a quality AHL level starter to be good enough to be a starter (suggesting that KHL is about on the AHL's level), would Michkov be given a backup job, or would something else happen entirely?
Here is my rankings of the different hockey leagues:
1. NHL
2. SHL
2.5 AHL
2.6. KHL
3. NCAA
4. WHL
5. MHL
6. QMJHL
Michkov was touted to be 2nd overall in the last draft except NHL teams didn't believe in him and he has KHL contract baggage so he falls to #7th. I know it's early, but it starting to show that he just had 1 exceptional year for MHL (20-21) where he scored 35 goals. I would expect him to be a barn-burner in a lower league like the KHL. He has all the tools to be a NHL superstar but his motivations might be in question. Look at his career stats, he is just AVERAGE. Before stating the obvious "KHL has superstars" it's worth remembering but there's very little parity in the K for teams outside of Moscow and apparently Magnitogorsk.
