I'm looking at the raw numbers of shot attempts against, then ranking them worst to first.

5v5 shots against - Panarin with 470. Only Kane on the Blackhawks has more.
He's also second worst in unblocked shot attempts against with 364.

I have no idea what you're looking at. He starts a ludicrous amount of time in the offensive zone, and has 49 defensive zone starts this SEASON (again, 1.23 defensive zone starts per game). That's not Selke stuff.
His line takes a huge volume of shots, which gives him a nice relative number, but he's not actually suppressing a damned thing. Considering how far he starts his shift from his own goal, it's beyond me how you can claim he's good at it.
