i think there is 3 options for the top 6 without Laine;
Anderson will probably gets the opportunity to play on the 2nd line. They will try to give him time and good line mates with the hope that he will find his game back.
Roy is a good fit because of his natural skills and his very good vision. I totally disagree with those who said that his camp was bad or that he wasn't implicated. He's a cerebral player, so his game is to analyse the play to predict what will happen instead of skating all directions. It isn't the first time that i see some fans from this forum that mix this kind of play style with lazy, un-implicated kind of players
Last option would be Kapanen because his good camp. ( he's also a good fit to play with Roy ) .
My ? concern is Newhook . Is he that good to pretend to be a top liner ? i am not sure. He seems to play a frisky game , trying to avoid any contact
