If Santana and Nolasco average 200 IP each and have a 4.30 ERA....which is about the career norms we cut 44 runs off our total from last year (assuming the starter ERA was 5.30 which I think is in the ballpark). That cuts our differential from 62 down to 18. That is before any benefit of May, Meyer, Sano, Buxton, or Berrios is layered on. I think he would provide innings, talent, and fewer runs. And be an additional barrier from the likes of Pelfrey, Pino, etc.
