Yeah Freo and Ross Lyon are a pain to deal with, but if they are serious about winning a flag soon and Sheridan wants to return to Vic, a straight swap for Yarran is win-win for both teams.
Thats just the point, They will only deal if they are left with no choice, In regards to a win/win I think if you were to ask any freo supporter they wouldnt trade Sheridan for Yarran if they didnt have to.
