It is the era of up-tempo, explosive offenses in college football, and records for scoring production are threatened or broken on an almost weekly basis. Nine teams averaged at least 40 points per game in the 2013 season, including six teams from "big five" conferences. There were as many 50-PPG offenses last season (Baylor and Florida State) as there were 40-PPG offenses four years earlier (Houston and Boise State).
We account for strength of opposition in our Offensive FEI (OFEI) ratings, a measure of scoring efficiency by possession based on starting field position. The top offenses according to OFEI are productive not only in terms of raw performance, but also have exceptional production against elite defenses. Florida State led the nation in baseline offensive efficiency last year, but since the Seminoles played only the 64th-toughest set of opposing defenses, their OFEI was a more modest No. 12 overall.
Which teams are projected to have the best opponent-adjusted offenses in 2014? Our model starts with a five-year measure of offensive success, Program Offense, which has a stronger correlation to next-year success than any other baseline factor we have tested.
As such, here are the top five offenses of the past five years according to opponent-adjusted Program Offense, and a breakdown of the challenges each will face in producing elite efficiency again this fall.
Program Offense rank (over past five years): No. 1
2013 Offensive FEI rank: No. 10
In 2013, the Bears led the nation in points per game for the season (52.4), their third straight season ranked in the top five nationally in scoring offense and in the top 10 in opponent-adjusted offensive FEI. However, their dominance early on in 2013 gave way to inconsistent production down the stretch. Baylor averaged at least 10 yards per play on 42 percent of its offensive possessions through the first seven weeks of the season, but posted a more modest explosive drive rate of only 21.4 percent the rest of the year. Oklahoma State held Baylor in check in its only regular-season loss (in late November), as the Bears punted on five of their first six drives against the Cowboys after having four or fewer total punts in eight of their previous nine games.
