Because there are already 3-5 candidates for that spot, and they have no LF, CF, SS, DH on the roster, and maybe no C......that's the biggest downside for me. Brock, he has three years with an ERA over 5, one with a 4.74, and two with an ERA under 4. What are the odds he pitches better than Gibson, Deduno, Meyer, Diamond, Worley....asked another way, what are the odds he pitches so much better than them that it matters in the outcome of games? If you have limited resources, how to best spend your money is an issue......or maybe we think they don't have limited resources, and this signing is not what is keeping them from signing any offense.
