Brennan finished 6th in Heisman Trophy voting in the 2006 Heisman race, behind Troy Smith, Darren McFadden, Brady Quinn, Steve Slaton, and Mike Hart. During the season, Brennan passed for 5,549 yards and 58 touchdowns, both of which are school records, and the highest passer efficiency in the nation. 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, Brennan announced that he was returning to the University of Hawaii for his senior season. He didn't feel he was fully prepared for the NFL and needed another year to get ready. He returned to Hawaii as a Heisman front runner and one of the NCAA's most prolific passers. "Rivals.com" named him one of the top-10 quarterbacks going into the 2007 season.
