Armia can't score as of now, but wait until KK develops physically. I think it's possible that we see them play together for quite some time and I'm sure Armia will find his scoring touch then, he just needs KK to be better which could come as soon as next year. While most here comments that KK should and will get better linemates later on, I feel that Armia is a good option for playing with KK for much longer than most here.
Danault's still learning and he did failed on his defensive assignment in some key moments, but he's being asked a lot and doing a great job so far, much more then we would have imagined at the start of the year.
Drouin is obviously making many indefensible mistakes defensively. He had that insane game where everything went right and now everything is back to normal. He's a frustrating player that's for sure. However, he's one of the most skilled player on the team and I feel he's a very good 2nd line winger as of now. He should have a different role on the PP though, it's just not working there with him. I am not overly worried with him, he should just have fewer assignments once our prospects develops and we have other options up front.
