Have to agree. If both were under contract for next year, then a swap could be on the cards. However as both are OOC then either can move without the need for the other to go in the opposite direction.
Personally, I've been resigned to the fact that we're likely to lose players such as Gaskell if we spend longer than 2 years outside of SL. The only real hope I can see of us keeping him and the other players considering moves is dependant on the new coach and what he brings to the club.
