In a second.
Pavelski is one of the best faceoff guys (to replace/join with Datsyuk and his 56% FO level), a right handed shot.
A shoot-first player, great defensive play, penalty kill. Babcock would love him.
I could say, Pavelski is equal player at 5-on-5 hockey, but on special teams (both PP and PK) he is by far superior piece compared to Filppula and also that Faceoff specialist.
Same age, cheaper contract. Just a no-brainer.
