He's a "zero" player. It's a sports philosophy where you try your absolute best to minimize mistakes rather than trying to get points, playing a system, or some other goal. It works well at the professional level. He should be a rock for us.
He's a defensive defenseman with a good understanding of the game. The biggest issue is people want a Keith, Doughty type d-man (fully developed d-man with no flaws) when even the so called solid offensive d-man have holes in there games (ex. Subban, Karlsson, Ekman Larsson, ect)
Ekblad may be the next franchise d-man, but when people talk about Larsson it makes me cringe thinking that
a) they felt Hall was going to get you any of the best d-man there, without failing to consider how long it takes to develop a d-man. (An analogy would be if you were to build a car from scratch you know that labour is the part that makes you inflexible of lowering price when in some jobs it's the meat and potatoes of the job).
b) they make it like it's all or bust. Ask Oiler fans what it would take to move Mcdavid, or Pittsburgh Crosby. Then ask teams with #1 d-man what it would take to get Doughty, Ekblad, even second tier highly rated d-man like Faulk, Hanifin, Bogosian.
Last year you seen it with Bogosian, Seabrook teams will lose forwards, before losing a d-man. Count how many forwards Chicago has lost from there first cup run then d-man. They retained 50% of there d-man (Keith, Seabrook, Hjalmarsson) forwards - Kane, Toews, Hossa (25% of there forwards). Ironically the best d-man in the league also come with NMC. Now that they are the template, don't be surprised if the Oiler's develop similar or close type players to have them have NMC.
