No way he becomes a more offensively complete player than Flip. And that assist number is crazy, look at his career.
Aside from the obvious post just to knock Filppula, he scored 10 goals in a little more than half a season last year and the season before that he had 14 assists with a full season. Playing with Z and Pav for a whole year and getting some confidence/experience, I could see him doubling those numbers. I'm not saying it absolutely will happen, but it's more than possible.
