I could see both Oakland and Jacksonville wanting Mays. Oakland is kind of a running joke because Al goes for the big time athletes. Jacksonville needs safety help, but if you look at their drafts since Jack Del Rio became HC, they have drafted a lot of guys based purely on potential.
As for Spiller, if Seattle doesn't draft him at 6 I don't see anybody but Seattle at 14 taking him (I don't think we'll take him. The only offensive player I think we consider at 12 is Dez if he's there)
