YPPSYS COLLEGE FOOTBALL RATINGS AND RANKINGS - DIVISION I-A (FBS) through November 1, 2009, after Week 9 games

YPPSYS COLLEGE FOOTBALL RATINGS AND RANKINGS - DIVISION I-A (FBS)
based on net yards per play advantage (NAYPPA), strength of schedule, defense and adjustment for losses through November 1, 2009, after Week 9 of regular season games

NAYPPA = net yards per play advantage
YPP OFF = net yards per play gained on offense
YPP DEF = net yards per play allowed on defense
Schedule = Schedule difficulty thus far in the season according to Massey Ratings (SchP=Schedule Partial)
YPP Statistics are from cfbstats.com
To obtain the Rating from which the Rank is calculated, one starts with the YPP OFF, subtracts the YPP DEF, subtracts the difficulty of schedule as a variable calculated as 1/100 of the schedule rating so that for a schedule rating of 18 for example, .18 is subtracted (rounded up or down to the nearest figure, here rounded up to .2), and for each loss .2 is subtracted. For Arizona, for example, we start with 6.2 as YPP OFF, subtract the 5.1 of the YPP DEF which is then a NAYPPA of 1.1. A penalty of .1 is subtracted if the defense allows 5.0 or more yards per play, .2 for more than 6.0 yards per play, and .3 for more than 7.0 yards per play. For Arizona we thus substract a .1 penalty for defense from the NAYPPA. Then we subtract the .2 for schedule rating and .2 for each of the two losses or .4 together, which results in a rating of 0.4 total or a rank of 17. In the case of equal ratings, the team with the toughest schedule is ranked first. One point of rating difference is equivalent to 9 points on the scoreboard.
