PROBLEM: Question: Which university's football team that Bradford played against after his return had a better 2009 season record? Passage:However, before the season began, Gresham suffered a season-ending injury. During the season opener against BYU, Bradford suffered an injury to his shoulder that forced him to sit out the next several games. The Sooners would go on to lose that game and their fourth game against Miami. Bradford returned for game number five against Baylor, but reinjured his shoulder the next week against Texas, ending his season and giving the Sooners their third loss of the season. The Sooners would continue to suffer many injuries throughout the remainder of the season including losing offensive linemen Jarvis Jones and Brody Eldridge, and defensive players Tom Wort, DeMarcus Granger and Auston English for the season. With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games. However, the Sooners would also lose all but one of their away games. Oklahoma ended the regular season with seven wins and five losses (53 in the Big 12). The game marked Oklahoma's third appearance in the Sun Bowl. They were a perfect 2-0 in their previous games. In 1981, they defeated Houston 4014, and in 1993, they defeated Texas Tech 4110.
