StrÃ¥lman is a huge part of Staal's re-emergence this season. Staal was fantastic when paired with Girardi/RozsÃval, but struggled mightily when he had to play with MDZ/Bickel/Eminger/whoever. Staal is a great defensive defenceman who has some decent offensive tools, but his transition game isn't very good. Paired with StrÃ¥lman who is all about a poised, calm, breakout they are performing great.
Strålman OTOH benefits from Staal as he himself struggles mightily with big, fast, skilled forwards who can just blow by him (Malkin, Kopitar, etc.) but Staal is one of the best in the league at defending against that type of forward.
I have to say I've been very surprised of the lack of offensive production from the pairing though. They have dominated possession so there have been plenty of scoring chances with them on the ice. Strålman apart from his weak shot is probably our most skilled defenceman and Staal has a booming shot.
All-in-all, this pairing needs to be kept together and apart from Zuccarello/Kreider Strålman is the most important re-sign this summer. Staal should be extended as well, and this is where their lack of offensive production helps us: I think we could get as much as a $1M discount on both contracts due to their disappointing offensive numbers as I think they are both 20-30pt d-men in a normal year.
