I agree Petan would have been better served spending a full 2 seasons in the A, over bouncing between the A and NHL. He has never taken a big step in his development, and I am sure this has something to do with it.
But players have to fight through that, it has happened to many players thru the history of the NHL, players to good to be AHL players, but not skilled enough to crack the starting lineup at the NHL level. Some players handle it the right way, learn on the fly and use practices as best they can to develop, while they wait for their shot.
One thing I saw early with Nic, his draft +1 when he played at the World Jr. that made me weary of his demeanor. It was the gold medal game, the game after he scored his hat trick. He was on the top line with McDavid, and in that first period, he had 3 really awful shifts. What I saw from the point on was a player that tried to force his game when it was not working. He held on to the puck way to often, made bad decisions and was taken off that line for the next 2 periods. On the 3rd line for the rest of the game, he continued to try and force his game when it was clearly not working for him.
After that game I thought to myself, how will this kid handle things not going his way at the NHL level. IMO he has somewhat continued that trait into his NHL career. He has yet to figure out how to translate his skills into being a consistent NHL player, and to stop trying to fit his jr game into an NHL game.
A grittier player like Lemieux, while he might not have the higher skill Petan has, he can consistently bring an element to each and every game he plays. It is much easier to be a hard hitter, corner digger player than a skilled player consistently, which is why we tend to see that type of player on a 4rth line. Its easier to be a grinder for 10 minutes a night that to be a skilled play maker with similar minutes.
This is the first season where I have watched Nic and seen signs of an NHL player. I thought his last game played was one of his best. I have no issues with him being in the lineup over Lemieux, and vice versa. A case can be made for both, and just because you prefer one side to the other, doesnt make either wrong.
