Yeah, I'd make that trade in a heart beat.
I would do that at the end of the offseason, if they can't get anything better for their expiring contracts, but it seems like a very lateral move to be making this early in the offseason, unless there is more to it.
As much as I want to get rid of Tony, I just am not sure Green is that much better...and he has an extra year on his contract.
So if they can't do better by September, then sure, lets bring in Green, and hope he is at least a little smarter than Tony, but until then, I would hope they can concentrate on finding someone who helps the team more.
