I think the point of dealing Lee to resign Green would be to play Green with Barnes. I just don't see them getting desperate enough to come to that, especially since their ownership has said that if it comes to paying the tax, that's something they are prepared to do. So, dealing Barnes is way down on the list of alternatives.
1. Trade a pick with Lee to move him.
2. Stretch Lee's contract and save about $10M of space this season and absorb about $5M each of the next two seasons after the cap goes up.
3. Eating the tax this year and then try to get back under it after the cap increases so you never have to worry about the really harsh repeater taxes kicking in.
4. Trade Barnes along with Lee to move him.
Even at #4, I think they will expect some type of additional compensation coming back to them to make them do it.
