Yes, I'm putting a team on my ballot that hasn't won a game yet. But if your two opponents are Iowa and Oklahoma, and you conclude that both of them are worthy of ranking, is Iowa State not a candidate too? I think so -- they only lost by 10 against both Oklahoma and Iowa, which might show a fringe top 25 quality side. My other reason for putting them here is a personal philosophy of ranking; it is better to rank teams that lose by somewhat close margins than it is to reward teams who munch on cupcakes.
