I'm sure Tigers would be happy to swap Galvin for DCE.Probably in everyone's best interest if they can get a decent trade player out of it for an early release.
As much as Galvin very much looks like the bad guy right now he's an impressionable dumb kid (if things are as presented) but good to watch on a footy field. Get him playing somewhere else but Tigers should hold out for fair compensation and he can take his lack of faith to reserves/flegg until then.
With this much noise do we assume, like you say, a competent club isn't on the other end. So...
Brown to Newy, Galvin to Eels, ??? from Newy to Tigers?
Not sure what that trade could be though - Lucas maybe?
