The Napkin Rankings enter Week 5.  If you haven't read the earlier posts, the Napkin Rankings are a quick and easy way to rate teams based on actual performance, not on whatever system the polls are using this week. Let's put it this way:  last year's national champion, Auburn, was unranked in the preseason polls.

You get a point for a win against a FBS team, a point for a win against a BCS team, a point for a win on the road (Neutral site games are 0.5 points), and a point for a dominant (30+ points) win.  You can't get the dominant win points unless the team you dominated has won a game, though - and the dominant point is the only point you can get when you play an FCS team.  You lose a point for a loss (away losses are 0).

Here's the best teams by conference.

ACC:  Georgia Tech, 10 points.

Big 12:  Texas, 8 points.

Big East:  3 teams tied with 6 points.

Big Ten:  Wisconsin, 8.5 points.

Conference USA:  Houston, 8 points.

Independents:  Notre Dame, 7 points.

MAC:  Ohio, 5 points.

Mountain West:  Boise State, 4.5 points.

PAC 12:  Stanford, 9 points.

SEC:  LSU, 10.5 points.

Sun Belt:  UL-Lafayette, 6 points.

WAC:  Hawaii, 5 points.

Here's the top teams in the nation:

1.  LSU (10.5 points)

t-2.  Alabama (10 points)

t-2.  Georgia Tech (10 points)

t-4.  Clemson (9 points)

t-4.  Stanford (9 points)

6.  Wisconsin (8.5 points)

t-7.  Michigan (8 points)

t-7.  USC (8 points)

t-7.  Texas (8 points)

t-7.  Houston (8 points)

The worst team in America?  It's a duel between Western Kentucky (-4 points) and New Mexico (-4 points), although since Western Kentucky has played less games, they can still take the "lead".  Plus, New Mexico just fired a horrible coach, so there's still hope they can win a game this year.
