Based on actual results of what the pitchers have actually done at the ML level, if we signed Saunders, he'd likely be our best starter this year...better than Pelfrey, better than Correia, likely better than Worley, likely better than Diamond.
-Diamond has ONE year under his belt, posted an ERA over 4.00 in the 2nd half. He and Worley are the only ones who MIGHT be better than Saunders, but they are unknowns. No real history.
-Pelfrey is coming off TJ surgery, and in two of his last three years he posted ERA+ of 78 and 81.
-Worley has never pitched even 135 innings in a major league season one year, didn't pitch well last year, and was then hurt. We don't know what we have there.
-Do I even really need to explain Correia, Deduno, DeVries or Blackburn?
As far as Meyer and May, they won't be here.
As far as Gibson he hasn't throw a major league inning yet.
Now, it's not like Saunders is a stud, but he's got a track record of being pretty decent, slightly above average while pitching a good amount of innings. Who else can we say that about in our long list of candidates? None of them
