LAS VEGAS LINES AND ODDS

The sports books opened Stanford vs. Arizona State with the Cardinal favored by 16 12 points and the spread has stayed steady right at Stanford by 17. The slight change in the line reflects that early bettors have laid a bit more money down on Stanford than Arizona State to cover the spread.

Vegas lines and odds aren't meant to be predictive. They are made to entice betting in equal portions on each side of the spread. However, combining the line and the over/under usually ends up close to some computer models. After all, Vegas is very good at this and it is a lot of fun.

Combining the line and the over/under, the Vegas combo has Stanford winning 38-21.

PREDICTIVE RANKINGS

Some computer rankings are designed to provide a built-in predictive element by comparing the ratings of two teams.

Some of the best ratings out there come from Football Outsiders. The most famous is Jeff Sagarin's for USA Today, previously used in the BCS computer rankings. I've included a couple others from around the web as well.

FOOTBALL OUTSIDERS F/+

F/+ is a combination of Bill Connelly's S&P+ and Brian Fremeau's FEI ratings. The ratings are usually pretty solid in factoring all the many variables involved in ranking college football teams that have a relatively low level of common opponents.

F/+ does not predict a final score but does give an expected margin. F/+ likes Stanford by 8 12 points with a 68.9% Win Probability.

The F/+ ratings list Stanford # 13 and Arizona State # 62.

Football Outsiders site only lists the ratings in order, but Bill Connelly posts predictions on SB Nation.

Bill's S&P+ picks predict The Cardinal by 18.6 points (winning 42.2-23.6) and give Stanford a win probability of 85.8%. Connelly picks Stanford at -17 to cover the Vegas spread.

SAGARIN

Stanford is ranked #18 with a rating of 84.96.

Arizona State is ranked #60 with a rating of 72.00.

Sagarin’s formula currently values home field advantage as worth 2.41 points. So subtracting the difference between the ratings and then adding 2.41 in favor of the home team, Stanford, Sagarin has Stanford favored by 15 12 points (15.37).

BILLINGSLEY

Billingsley's ranking was also previously used by the BCS. With the BCS restriction to remove margin of victory no longer a consideration, Billingsley has created a version of his formula that accounts for margin of victory.

Stanford is ranked #19 with a rating of 102.445.

Arizona State is ranked #54 with a rating of 96.052.

The difference is 6 (rounded down from 6.393) points. Billingsley does not provide a home-field advantage factor, but let's apply the standard 3 points to the Cardinal and say Billingsley has Stanford by 9 points.

DONCHESS INFERENCE RATING

Donchess boils down the ratings directly into digestible scores and probabilities, no math required.

Donchess predicts a Stanford win 40-23 and gives Stanford a win probability of 88.6%.

ESPN FOOTBALL POWER INDEX

FPI has Stanford ranked at #9. This week’s opponent, Arizona State, is #52.

FPI doesn’t provide a prediction as far as a score but does give a win probability. FPI suggests that Stanford has an 80.8% win probability over Arizona State.

COMPOSITE RATING

There are a lot of computer ratings that aren’t packaged with a predictive ability. There are also a ton of computer ratings, period. Kenneth Massey, whose ratings were also part of the old BCS computer formula, hosts on his site a composite ranking of 106 computer ratings across the internet.

In that composite, Stanford ranks #25 and Arizona State ranks #55.
