I'm quite happy with the choice to send him down. Watching the Eerie game, it's clear he's among the best players in the OHL right now, but it's still the appropriate level for him. His game is based on counter attack and exploiting mistakes, which is what you expect from a kid playing with pros (they have to eat what they kill or scavenge). But he has a long way to go before you can claim that he's ''beaten'' the league. What I want to see more from him is not just exploiting the weaknesses in the opponent, but actively picking sound defences apart.
I can understand the reasonning for him being in the OHL. It's the best decision 90% of the time for guys in his situation, with his size.
What I'm weary of is that highly adaptive guys like Mesar always slow down or speed up to adjust to the requirements of their environment. I'm afraid that, as time goes by, he will slow down his pace and decision-making.
I haven't watched him in the OHL outside of a few clips and highlights, so this is just an uninformed opinion. I can say that the pattern we've seen in the small sample size (if there is a pattern) is moving along that direction right now. First few games in the OHL, his brain is still working at NHL camp/AHL speed. The results follow. Next few games, brain slows down to the requirements of the game, his play starts to "fit-in" (if that makes any sense for you).
Sample size is extremely small, so that remains to be seen whether it will the case or not. We'll see in a few months, but I just wanted to put this out there as a clue to add to the equation aside from the usual assessments like "see, he wasn't ready for the AHL as he's still got a lot to learn in juniors" or "he's killing it, too good for juniors".
Maybe people who regularly watch him can tell us, as the year progresses, if his play "slows down" or not.
