Correct move is Twarynski to 4LW, Raffl to 3LW, Pitlick to 4RW.
Give Vorobyev a few more games to show he belongs in the NHL.
Rubtsov and Frost need to marinate, Frost would be a question mark at LW, he didn't look comfortable playing there in the WJC, so why force the change on him - if Patrick turns out to be career threatening, we need to groom Frost to be the 3C, maybe as early as January.
If Vorobyev is a "fail" after 10 games or so, I'd expect Rubtsov to get a shot at 4C.
NAK? Up to him to impress the powers that be to give him the same shot as Twarynski and Bunnaman - it's not like Pitlick/Stewart are an insurmountable roadblock to a promotion.
