And just to elaborate on Pedan ...
To me, I look at scouting defenders and the skills your looking for as an inverted pyramid, where you have one foundational skill - hockey sense/IQ which normally correlates with both positional sense and quality puck distribution on the breakout - at the base, followed by two more foundational skills (mobility/footwork and size/reach) just above it.
Above those are a bunch of 'fluff' skills which are great if the player has the foundational skills in place - hitting, shot, fighting, forward skating and puck-rushing ability, PP QB skills, etc. - that form the 'top' of the inverted pyramid. However, if the defender doesn't have the foundational skills, these skills (which normally catch the eye of the casual fan the quickest) are pretty much useless. Jack Johnson is the primary example - skates like the wind, hits like a truck, cannon of a shot ... can't process the game quickly in his own zone so he's completely useless. And we see this with Sbisa here as well.
To me, when looking at defenders, you have to scout from the bottom up in terms of this pyramid. My frustration on Benning is that for every single defender he's targeted, he seems to be captivated by fluff skills and be scouting from the top down. In other words, I don't think he has a ****ing clue how to scout or project NHL defenders.
In Pedan's case, I see a guy with huge deficiencies both in terms of his hockey IQ/game processing and in terms of his footwork/skating. I can't envision this player succeeding in the NHL when he's that fundamentally flawed, no matter how big/tough/somewhat puck skilled he is.
