Im not a fan of breaking guys off of their natural positions either, especially when those guys are scoring wingers, have produced well on their side and have been there for a long time.
I think its forcing the issue a little bit, though I like the idea of separating Gaborik and Nash. I also like the fact that he wants Hags on the first line, I think it sets off the top two lines very well and Richards works well with Hags and thats part of the reason.
But if you keep Nash and Gabby on their own sides why not have Cally on the top line instead and do:
Nash - Richards - Cally
Hags - Stepan - Gaborik
?
There is a slight chance, a very slight chance that having Nash and Gabby play on their off wings could be a positive due to the linemates they have. You could catch that lightning in a bottle for a little bit and ride it.
It also may be Torts' way of getting Nash and Gaborik to be more well rounded in the system, but Im under the assumption (especially for unique, star players) that you put them on the ice and you just let them go. The last thing you want is to have them overthink out there because it could lead to a slump or even injury if you arent careful. When you finally change them back to their own wings it might take a while to get it back then.
Big risk if you ask me. Torts is forcing it. Hopefully they suck terribly today in camp and he switches them back.
