Not to seem like I'm picking on Tennessee with my post below about how Tennessee's 2009 offensive numbers fall when you take out the WKU outlier game, here's a look at how some ranked teams fare when their outlier games are removed. The outlier games are either against I-AA teams or simply bad I-A teams (as is the case with WKU).
The Outlier column below indicates the opponent, score of the game, and the total yards gained by the team.
|Team||PPG||YPG||Outlier||PPG Adj.||Difference||YPG Adj.||Difference|
|Florida||45.5||526.25||CSU, 62-3, 624||40.0||-5.5||493.67||-32.58|
|Texas||49.5||521.25||UTEP, 64-7, 639||44.6||-4.9||482.00||-39.25|
|Alabama||40.5||490.50||No. Texas, 53-7, 523||36.3||-4.2||479.67||-10.83|
|USC||28.8||430.60||SJSU, 56-3, 620||22.0||-6.8||383.25||-47.35|
|Cincinnati||42.0||468.20||SEMO, 70-3, 578||35.0||-7.0||440.75||-27.45|
|TCU||34.8||423.50||Tex. St., 56-21, 508||27.7||-7.1||395.30||-28.20|
|Oklahoma State||39.0||419.75||Grambling, 56-6, 587||33.3||-5.7||364.00||-55.75|
|Oklahoma||35.5||424.75||Idaho St., 64-0, 564||26.0||-9.5||378.33||-46.42|
|Ole Miss||32.5||373.50||SELA, 52-6, 500||26.0||-6.5||331.33||-42.17|
|USF||37.0||413.60||Two I-AAs, 99-7, 906||28.7||-8.3||387.33||-26.27|
As you can see, teams like USC, Cincinnati, TCU, Oklahoma, Ole Miss, and USF lose about a touchdown or more when adjusted, and four of them lose 40 or more yards per game. This is why stats can be so misleading, especially early on in the season.
