[A] net increase of 5-7 wins is reasonable assuming everything else remained constant.

Eminently reasonable! That's where I came up with 5-6 net wins, because I think Santana does represent a substantial upgrade to the Mets' rotation.
And MacNut--if you think that about the Mets, I can only imagine what you'd have said about the Rockies last year.
