I know everyone wants to give up guys like Portobello and Cecil for good talent, but thats not going to happen. If we're talking about 25-man roster guys, it has to be someone of value. Edwin fits the profile of a good trade candidate.
He has 1 more year remaining on his contract, and he's still producing. We have a suitable replacement for him (obviously not as effective, though) and we are dealing from position of strength (offense).
The only problem is to find a team that needs offense and can deal excess pitching.
aaaaaaand I just realized one problem. Edwin gained his 10/5 rights a few weeks back. He'd have to OK the trade :/
