Colt Brennan joined
Hawaii in 2005 and quickly grabbed the starting spot at quarterback. He started 10 of 12 games, the only games he did not start being against
USC and
San Diego State. Brennan either tied or broke 11 UH offensive records in what was a wildly successful first season with the Warriors. Brennan led the country in total offense yards (4,455) and touchdowns thrown (35). His 4,301 yards passing is the eighth-most in
Western Athletic Conference (WAC) history. Against
New Mexico State (Oct. 15), Brennan posted career-high numbers in passing yards (515), touchdowns (7), and pass completions (38). He also had nine 300+ yard performances on the season, including four 400+ yard games and a 515-yard performance.
Brennan entered the
2006 season as the undisputed starter at quarterback, was named to multiple award watch lists and was voted the WAC's preseason offensive player of the year. He led the nation in scoring and
passing efficiency, finishing the regular season with a 182.8 rating, and completed 72.15% of his passes, the best mark in Division I-A.
During the regular season, Brennan passed for 53 touchdowns, one shy of the NCAA Division I-A single-season touchdown record of 54 (set in 1990 by
David Klingler of
Houston). On December 24, 2006, at the Hawaii Bowl, Brennan threw for 5 touchdowns to break the record. (Statistics accumulated during the postseason now count towards records.) The
Warriors finished the season with a 11-3 record, placing second in the WAC behind
Boise State.
Brennan finished sixth in the 2006
Heisman race, behind winner
Troy Smith, Darren McFadden, Brady Quinn, Steve Slaton, and
Mike Hart. During the season, Colt Brennan threw for 5,549 yards, 58 touchdowns, and the highest passer efficiency in America. According to Jones, "Colt is a money guy. Colt is what I said he is: the best college quarterback in America, and he proved it tonight." During a press conference on January 17, announced that he was returning to the University of Hawaii for his senior season. Brennan didn't feel he was fully prepared for the NFL and needed another year to get ready. Brennan will return to Hawaii as a Heisman front runner and one of the NCAA's most prolific passers.
