I get that the early returns on Miro are very promising, but it's been 4 games in the MHL. Might need to pump the brakes on the hype train a bit. He's actually playing in a lower league than he was last year (the VHL). For context, in the handful of games that Kuznetsov played in the MHL, he was nearly a 2PPG player (31 points in 17 games spread across ages 17-19, the MHL didn't exist when he was younger than that). Heck, even Orlov put up 13 points in 8 games in the MHL across his age 18-19 seasons. Nikita Gusev had 192 points in 120 MHL games, and he didn't end up working out as an NHLer. The best example for hope would be Nikita Kucherov, who had plenty of MHL time and not a lot of KHL time, but even he had one season in the Q (and dominated the WJHC) before joining the NHL ranks. Kucherov had 43 points in 23 MHL games in his D+1 season.
None of this is to say Miro is bad or Miro won't pan out. Just that it's awfully early to start getting excited, and certainly too early to envision him on an NHL 1st line. 1st line NHL talents should be absolutely dunking on the competition in the MHL, but unfortunately so do some players who arent 1st line talents.
