THE 2009 YPPSYS (TM) PRE-SEASON DIVISION I-A (FBS) COLLEGE FOOTBALL RATINGS and RANKINGS PREDICT A USC NATIONAL CHAMPIONSHIP

We predict a USC national championship in 2009, based on the YPPSYS Ratings and Rankings.

THE YPPSYS (TM) DIVISION I-A FBS 2009 PRE-SEASON COLLEGE FOOTBALL RATINGS and RANKINGS are based on performance ratings and rankings from the preceding season. Yppsys ratings and rankings are a YPP SYStem (yards per play system) primarily determined by four variables: 1) the net average yards per play gained vs. lost by the offense and defense of any team; 2) strength of schedule; 3) weakness of the defense; and 4) won-loss record. These figures must be adjusted for each team as the season progresses.

• NAYPPA (TM) (Net Average Yards Per Play Advantage) is calculated according to statistical data available at CFBSTATS.COM. A team that gains 6 yards per play on offense and gives up 4 yards per play on defense has a NAYPPA of 2.0 - enough some years for a national champion.
  
• Schedule Difficulty is the ranking according to Massey Ratings. A multiple of .01 of the schedule ranking (rounded up or down) is subtracted from the NAYPPA of Division I-A FBS schools. For Division I-AA FCS and Division II schools the schedule difficulty multiple is .015 and for Division III schools and the NAIA the multiple is .02. For example, if a school has a schedule difficulty which ranks it 50th in the nation, then .01 x 50 = .5 which is subtracted from the NAYPPA, in the example above 2.0 minus 0.5 = a rating of 1.5
• Weakness of Defense Penalty. If a team allows 5 or more yards per play on defense an additional .1 is subtracted from the NAYPPA; if 6 yards per play or more are allowed, then .2 is subtracted,; if 7 yards per play or more are allowed, then .3 is subtracted. For example, if the team above with a rating of 1.5 gave up 5.2 yards per play on defense then .1 is subtracted from 1.5 to give 1.4.
  
• Win-Loss Record. For each loss .2 is deducted from the NAYPPA. For example, if the team above had a record of 12-1, i.e. losing one game, then .2 is subtracted from 1.4 for a final rating of 1.2, which in 2007 was high enough to mark the national champion.
  
• Predicting Games. ONE point of rating difference by NAYPPA = 9 points on the scoreboard. Note that Massey Ratings calculates the home field advantage at an average of 2.68 points whereas Sagarin uses the rounded figure of 3 points.
