He's elite top tier for defensemen offensively and as others have pointed out that was more ES than PP to boot. Sure he could use some work on the defensive side of things but it's not nearly as bad as some of you are saying. He can improve and with a better partner we will see how he fares. But he's so gifted offensively that the deal is absolutely worth it, and is only 2 years taking him to RFA. There's the risk that he keeps this up or does even better and costs a fortune should we keep him, but it was the right move to limit term and see where it goes. He put up 30 in 60 the season before last, too.
And though I won't get into character details I will say that he's loved in the locker room and consistently named as one of funniest guys. Not to mention he stands up for teammates and plays with an edge.
This is a good deal to make at this point in time, period. Impossible to predict the next two years but as it stands it's hard not to like this.
