I feel Sharangovich has a pretty solid defensive game. Having two gamebreakers out there on the PK in Nico/Yegor adds something to your PK where you don't want to turn the puck over in a bad way against them. I don't mind him on the PK at all.
I feel it shouldn't be understated that a PK with Boqvist/Vesey is a lot less intimidating than one with Nico/Sharangovich and you're gonna get good play out of both units. However I trust one duo a lot more with the puck on a fast break offensively than the other.
Ya, Shara is getting a bad rap defensively. The numbers aren't great, but like Nico in years past where people wanted to say he wasn't good defensively because of his underlying #'s, and then one year the numbers catch up to the eye test, I think similar could happen with Shara.
Not that I think Shara is an ace defensive fwd currently, but I think there is something there.
I also agree that having scoring threats on the PK puts pressure on the opposition PP. We certainly saw that back in the day when Parise and Kovy were sharking out there on the PK. Shara and Nico are not at that level, but I' do want to see if they can find some level of that.
Now I do think you underestimate the Boq/Vesey tandem (and yes I know Vesey is out). Boq is the best skater of the guys we are talking here, and I think he, like Shara and Nico could prove dangerous as a counter attacker on the PK, and again let's see how he develops. And Vesey was just good on the PK.
