Agree, his first step is slow and his skating stride is short and almost shuffling which limits into a short burst. Critical is his four way agility and area defending with size. The critical component is his processor maturing into decision making against fast, aggressive apex level competition. This is the critical speed of game gap of an immature prospect D. His skating technique can still be developed though it won't ever be a defining characteristic.
Unfortunately he's not a fit for Edmonton who have limited assets and a more urgent need for a veteran mature top 4 d-man to complete a Cup Level defense corp. I had proposed a hedge trade idea of going after Provorov and Jiricek as a package for immediate help and future, sustaining window acquisition with their 1st, Akey, and 2nd round picks. That would hedge the 1st for a UFA Provorov. But a poster rightly commented C-Bus likely gets more value selling off the two players separately.
I'd love a future NHL near ready high-end defense prospect in the system. But think there are teams better positioned to give up assets and deliver the opportunity required that we know from recent first hand experience is primary motivator for young players.
