The Napkin Rankings (a quick and easy way to rate teams based on actual performance) enter Week 6.  Teams get a point for a win, a win against a BCS conference team, a dominant win (30+ points) and a road win.  Neutral site games are half a point.  Here's a look at the best teams in each conference.

ACC:  Georgia Tech, 12 points.

Big 12:  Oklahoma, 10.5 points.

Big East:  West Virginia, 8 points.

Big Ten:  Michigan, 11 points.

Conference USA:  Houston, 10 points.

Independents:  Notre Dame, 8 points.

MAC:  Temple, 7 points.

Mountain West:  Boise State, 7.5 points.

PAC 12:  Stanford, 12 points.

SEC:  LSU, 13.5 points.

Sun Belt:  LA-Lafayette, 7 points.

WAC:  Hawaii, 5 points.

Here's the top 10 teams in college football:

1.  LSU, 13.5 points (Last Week: 1)

2.  Alabama, 13 points (Last Week: 2 - tied)

t-3.  Georgia Tech, 12 points (Last Week: 2 - tied)

t-3.  Stanford, 12 points (Last Week: 4 - tied)

t-5.  Clemson, 11 points (Last Week: 4 - tied)

t-5.  Michigan, 11 points (Last Week: 7 - tied)

7.  Oklahoma, 10.5 points (Last Week: unranked)

t-8.  Oklahoma State, 10 points (Last Week: unranked)

t-8.  Houston, 10 points (Last Week: 7 - tied)

10.  Illinois, Arizona State & South Carolina tied with 9 points (all previously unranked).

As you can see, the huge neutral site win boosted the Sooners into the rankings; also, Oklahoma State running up the score on Kansas earned them 3 points.  USC, Wisconsin (inactive) and Texas all dropped out of the rankings.

Since Western Kentucky won a game (on the road, no less), the worst team in the country is the New Mexico Lobos, who stand alone at -4.
