It comes from the hype pre NHL and after his 1st game. He has not met expectations and even if he is a good bottom 6F when he reaches prime, to some fans, that means he sucks.
I do admit, he is a difficult one to project forward. To cheap to say he sucks and is barely a NHL player.
Agreed, not many shine in the 20-25 age range and a lot of players like Poehling look much better in the 25-30 range. Problem is he came to the NHL with high expectations and because he has not met them, fans are frustrated with him. Typical Montreal
It's up to him to learn from his experience as he matures and work on the flaws in his game. Take time and we clearly know that he's not busting out. More like gradual gains here and there season to season.
