We're only 3 games out, quite to go before reaching critical mass. I really don't see them selling players, especially Lester, it complicate things further if they want to re-sign him as a free agent. But we're just 3 games out, would be great to start delivering timely hitting. They still have the 3rd best OBP in the AL.
I'm not a fan of Ethier trade. He's a platoon player, Nava could put up the same or better stats.
