Whole-heartedly agreed on the bolded. Karlsson is one of a kind - there is no defenceman in the league like him. He is a superstar in the league, the first true one Ottawa's had (Chara doesn't count as his true value was appreciated when he moved to Boston to win a cup). Players like Alfie don't get true appreciation in their prime - and he was on Iggy, St. Louis, and Lecavalier level in his prime. Spezza is also underrated, but not on the Crosby, Malkin, Ovi, or Stamkos level of stardom. Karlsson is actually up there with the true elites, and I see no reason why he can't repeat his performance from last season. EK's Norris win won't be his last, and I won't be surprised to see this guy get at least a nomination for the Hart in the future. Back in 2003, I was laughed at by my friends when I told them Chara would win the Norris one day. They also thought I was crazy when I jumped on the K-wagon. Naysayers, don't laugh when I say that a Hart nomination for King-K is actually very likely in the not so distant future.
I do not agree with your stance on Edler and Hamhuis though. If the opportunity presents itself, I would pick Edler over Hamhuis 10 out of 10 times. Ham n' egger's not worth $4.5/year in my books. Hopefully, Edler is given a long look by BM if he becomes UFA next season.
