Does Ginn return both KO's and punts? If so, I'd go with him, since the Pats will probably have several KO's to offer. If Ginn only does punts, then I would go with Davis here.
Also, if there is any way you can pick up MSW, do it...even if you don't start him this week. (would like to have seen your roster).
Thanks for helping on mine.
