I haven't seen enough of Laine to really pass a judgement on him, I will convey what Matt Barnaby and P.J. Stock have said about him on NHL radio. Neither likes him, both feel he is extremely lazy and self centered, while both agree he can score they do not view him as a true game changer or playoff player. Barnaby compared him to a lessor Alex Kovalev from his time playing with him in NY, tons of talent, not engaged.
Depending on the cost, both cap wise and return, I think he may be worth it but he comes with some warning stickers.
While older and me always a believer in take the sure thing now there is a part of me that says wait and gamble on Hall
