Longshore entered 2007 as the established starting quarterback. In the preseason, Longshore was rated as the No. 5 quarterback in the nation by The Sporting News and ESPN's Mel Kiper Jr. ranked him the 3rd best junior quarterback in the country. Longshore led the Bears to 5-0 start and a number #2 ranking with wins against #15 Tennessee and #11 Oregon, but suffered a sprained right ankle that resulted in a bone spur in California's close victory over Oregon. Longshore missed the Oregon State game, Cal's first loss. He returned to start the Bears' last six regular season games, but he and the Bears were not the same, winning only one game, against Washington State.
