I like Oleksiak, I think a lot of his issues are that he's moved from LD to RD, back and forth, and he's with the wrong D partner. He's a guy that would thrive with a defensive first kind of guy. I would rather see him with Pettersson than Johnson or Maatta.
But if people want Petrovic, cool, I hope it happens. He's elite at blocking punches with his face.
The problem is that defensive first kind of guy also needs to be a strong passer/puck mover, because you don't want Oleksiak being the best PMD on the pairing.
I know few are happy with the mix on the blueline, and while I'm not sure Oleksiak individually is part of the issue, I really do not think he's part of the solution. Especially since we need a very specific partner for him - and I'm not even talking about getting the best out of Oleksiak... just turning the pairing into something that doesn't scare the shit out of us whenever it's on the ice. Add in Maatta and JJ, and of those 3 I think Oleksiak is the easiest to move, the easiest to replace internally (TOI, not being someone we'd miss) and the least worry some if we f*** up the deal (cap space + a 3rd doesn't bother me at all, where as I'd probably be pretty pissed if we did that for Maatta).
