Kravstov has been much better as a LW than a RW. His stats as a RW in the KHL are pretty poor.
Kakko is effective all over so no worries there.
It's also very possible that a permanent move to wing is in the cards for one of Chytil or Andersson, maybe even both.
Tying up that much money (and roster space) is just a bad idea. I'd prefer that they keep both slots open unless they can get a second high pick/someone awesome drops to them for some stupid reason.
Plus its just unnecessary to tie up that much money in guys of that age at the moment.
I’d be a little cautious reading into those stats that much (albeit they are very interesting). I recon that he didn’t just switch sides with the same linemates.
