I don't see how they move Wallace without him building up some value by playing well after his dismal season.
Humphries is movable as an expiring contract but I can't see how we get anything better than just having him as an expiring contract.
Brooks is a cheap scorer and I understand there has been interest in him in the past, he is definitely movable and could be packaged with another less desirable contract.
Bogans I have no idea who he is but he is an expiring with the next two years not guaranteed.
