Thomas turns 25 this year and isn't much of a defender. His value is easily replaced by any one of Marquez Smith, Lemahieu, Flaherty, etc. Coello, IMO, moves near the top of the heap of middle relief options with his ability to get K's. I value that more than I do the middling skill sets that guys like Caridad, Gray, Samardzija, Coleman, Diamond, or Mateo have. Marqez Smith doesnt play second base, if he did end of discussion. I agree with northside blues of the three guys we have that can play second Baker, Dewitt, and Barney none are impressive. Thomas was a high ceiling pick originally but just hasnt put it together at the higher levels like he should have. still he has been solid, and I would have more confidence in him seeing extended time at second base and hitting mlb pitching then Baker or Barney. Either way he doesnt see the light of day with the BoSox unless Pedroia is still hurt.
