So far, we have six indicators that say Oakland, one that says Tampa Bay, one indeterminate (the 18-18 conference affiliations) and one that we still have to deal with -- the different kinds of humans. No matter how it comes out, Oakland will be ahead, 6-2 or 7-1.

For the record, here's how humans vs. humans breaks down.

Some arbitrary classifications are necessary for the sake of simplicity. The Jets are considered humans, as in the Jets and Sharks of "West Side Story;" the Chargers, as in credit-card users; and the Bills are named for Buffalo Bill, notably a human. If the Jets, Chargers and Bills are considered inanimate objects, they mess up my system.

"Animals" includes fish and birds. They've met only once, when the Broncos beat the Falcons four years ago.

Humans can be classified by occupation (Steelers, Cowboys, 49ers, Packers) and by some sort of "warrior" class. Those include Raiders, Vikings, Redskins and Chiefs (the last two referring to Native American warriors). Others simply are miscellaneous.

The Raiders and Buccaneers (pirates) are "warriors" facing each other for only the fourth time. The Chiefs beat the Vikings (IV), the Raiders beat the Vikings (XI) and the Raiders beat the Redskins (XVIII). So score this one for Oakland, making the final tally 7-1.

Last year it was 6-3 for the Rams, who lost to the Patriots.

The year before is was 5-4 for the Giants, who lost to the Ravens.

You have been warned.

Good luck.
