People say MHL is a bad league, but when you combined the stats of 15-16 years old season of Michkov and Demidov:
After 69 games, 29 goals, 56 assists, 85 pts, 1,23ppg for Ivan Demidov.
After 84 games, 68 goals, 39 assists, 107 pts, 1,27ppg for Matvei Michkov.
Demidov at 17 years old at MHL can't be compared to Michkov, because Michkov have been in KHL. But 2ppg in 30 games and 2,5ppg in his 19 last games, put a sequence of 3ppg in 7 games aswell, that's a huge step for his 15-16 years old season.
So yeah, MHL isn't bad like people think.
