While I hope that Perk can cut down on the turnovers (and I wonder how many of Perk and KG's turnovers this series are from moving picks), it is not so bad.
I think Perkin's passing in Game 2 helped fuel the win. He appears to be less of a black hole on offense and is looking to pass more. Because he is a center and not a point guard, he obviously is not as good of a passer as Rondo and will have more turnovers. Still, I'd argue that Perk looking to pass sometimes is a net positive for the team, even if he messes up sometimes.
(Although, after saying all of that, I think most of his turnovers are not from passing but from picks, travels and 3 second calls. But passing is still good.)
