It's hilarious. Even if you outline one single attribute that you think Laine has over Matthews (which he has plenty), the few people here come swarming at you with "there's noway in *** he can be better than Matthews!".
Whoever said that if Matthews scores 40 goals, then Laine scores 50 goals a season or a ceiling or whatsoever was pretty accurate. Laine is a lot more dynamic in the offensive zone and has shown some crazy craftiness, especially when he's being marked down. He finds a way to create a chances for the team mates by high creativity, vision and tape-to-tape passes, even from the back hand. When he eventually grows into the frame it's going to be pretty damn nasty trying to take the puck away from him. Matthews seems to have more direct approach, uses quick short passes to create space and has a pretty good shot himself, not Stamkos good but still deadly accurate. He's not nearly as lethal as Laine however, if you let Laine alone even for a moment, the puck finds a way to the center point. Especially in FEL playoffs, teams had to design their penalty kill units to stop him and Laine always managed to find new ways to get around the traps. People talk a lot about his shot, get blinded by it and often do not even realise how high hockey IQ this guy possess.
