They definitely have options now and his bonehead plays/bad defense are clear issues.
I still think he will/should find his way into the lineup if he hits. You can't be making dumb plays that cost the team runs so that does need to show improvement, but you also can't keep him out of the lineup if they found production with him.
With Robert and Benintendi in CF/LFE being unreliable and young players across the infield, there's still a spot for Sosa, but he has no value if he doesn't hit.
Is Mead part of the 3B mix for next season? If he is, that's a hole already. Is Vargas seen as 1B/3B?
They are still short at at least one of 1B/3B, LF and DH (though Quero/Teel can help), but just saying that a guy who hits should have an most everyday role in this lineup
