Duffey's curve ball is legit, there aren't that many adjustments one can make on him. He also has a very solid and consitent minor league track record and is only 24, which still puts him a couple years away from his prime. Heading into 2016 with no changes: I think Santana is our top pitcher, Duffey number 2, Berrios number 3, May 4, Gibson 5, Hughes 6, Milone 7, Nolasco 8. Berrios won't be up for a minute, but I already have him ahead of Hughes, Gibby, Milone etc. This is why I think Gibson and Milone should be shopped aggressively. (Nolaco and Hughes would take us eating a big part of the contract)
