I don't think the Frolik and Versteeg decisions had anything to do with each other.
And quite frankly, while I loved how Frolik completely remade himself into an amazing 4th line and PK specialist, one guy shouldn't be (and isn't) the reason the PK went from 1st to last. There's a systemic problem, because everybody on the PK is playing passive, giving way too much time and space to the opposing team. You don't need to be Frolik to pressure the points, or help your teammate outman guys on the boards, or get in shooting lanes, or generally just work your ass off. But nobody is doing that right now. When everybody on the PK starts doing those things, it will be good again, without Frolik.
I willing to give Versteeg more time before making the judgement. He's just coming off an injury that has caused him to lose a step.
I would like to see Q play Versteeg more on the PK and can't really figure out why he hasn't, but to be fair, the PK has been getting better since Handzus was put on it, so my guess is that will be status quo until it starts getting worse again...
More than anything though, I'm thinking they might need to look at fixing Saad onto the third line to play with Versteeg. Both guys seem to be getting bounced around the second and third lines lately, which can't be helping them find a rhythm... but every time Versteeg and Saad are playing together, good things happen.
The only way I can see that happening though, is if the lines shake out as:
Toews/Kane/Bickell
Hossa/Pirri(or Zus)/Sharp
Saad/Shaw/Versteeg
Without Bickell in the lineup, there's really nobody in the bottom 6 capable of moving up to play with the top 6 in order to allow for Versteeg and Saad to play together. At least not that I can think of at this hour...
