I wouldn't be so quick to assume Benning hasn't scouted Svechnikov at all. Even in person, i'd wager he has. I'd pretty much guarantee he's spent some time scouting him via video.
I've pretty much lost track of all the places Benning has popped up scouting (it's been pretty extensive). But i'd bet Cape Breton was on the dockett somewhere in that well noted QMJHL swing Benning did out in The Maritimes. In the same way he wasn't just scouting Boeser + Novak in Waterloo, but watching them vs Kyle Connor's team when he made his trip to Iowa the other day. Scouts love that stuff, watching top players head to head. It's efficient, and also a nice measuring stick. Same goes for all the OHL top prospects he likely caught while he was out there checking in on McCann, Cassels, Subban, et al a while ago.
Whether or not Benning came away thinking Svechnikov was "the right sort of player" for the Canucks, is another matter entirely...some questions there. But i would absolutely guarantee he's looked at him...probably quite a lot. He wouldn't be doing his job if he hadn't...especially for a GM who is very much a self-described "scout at heart".
He's not the sort of GM who is going to leave scouting stones unturned.
