I believe the Sox felt that Beni was becoming an average defensive outfielder with a declining hit tool and meager power. They are moving forward and got what they could. There is a risk that they have this wrong, but if they were right, the move was necessary. JBJ is also probably gone, especially if he is looking for 4 years. The Sox may well believe they need to rebuild the outfield and have candidates in house. I don't think the Sox are being cheap but are being smart and building for the future.
