Petrovic isn't that good: he's a full step down from Zaitsev and a half-step above Ozighanov and he misses a lot of time due to injury/scratching.
And also being that Florida is a divisional rival, we aren't getting him for Chris Wideman (who honestly I would take over Petrovic) and a 3rd. Florida would have asked something like young B prospect (think Engvall or Durzi), a young E prospect (O'Connell or McAdam types) and a pick on top.
We don't need a guy to perhaps challenge Ozighanov, we need a guy to push Zaitsev down.
...which is why after consulting with the oracle, I envision us being heavy players in the Alex Pietrangelo sweepstakes, and I'll part with anyone not named Matthews, Marner, Tavares, Rielly or Andersen with bells on, and I'd really prefer to keep Grundstrom, Dermott and Sandin.
My offer is Nylander + 2nd 2019 + Liljegren...or Kapanen + 1st 2019 + 2nd 2020 + Liljegren for Petro + something small.
