Both anyone come to you're mind that worth or close to his value.
Well then... Pacioretty is a former star winger that seems to be declining. Or at least has had a bad season. His contract is also an issue that lowers his value.
I'd say from proven NHL centers closest to his value are Nick Bjugstad (a little bit worse player but good contract), Adam Henrique (center who's finding his game phase + his contract is also about to end) and Charlie Coyle (good player but his role in Minnesota doesn't really let him shine in there).
From center prospects, I'd go for B-tier prospects, such as Aleksi Heponiemi, Nick Merkley, Tage Thompson and Sam Steel.
Alongside with these mentioned players, you can also try to acquire some draft picks.
You could also try to swap Pacioretty straight to a semi-high draft pick.
Obviously, depending on which team you're trading with, you can get a higher price.
