From a keeper perspective I'd rather be on the Gio/Gordon side. For win-this-year... it's close. So yeah, I'd take Gio/Gordon (unless you can only keep for one year or something, and then I'd think about it more).
this surely isn't waiving the white flag..it's entirely possible this gives you a better shot at winning this year, although all in all I'd say its a really even deal, even for a re-draft. Given the dynasty aspect, I'd say your sitting pretty!
