Steve Sarkisian intends to implement an uptempo offense at USC, and he added a key ingredient to that formula Sunday afternoon.

The Trojans picked up a verbal commitment from dual-threat quarterback Jalen Greene (Gardena, Calif./Serra), who recently decommitted from Boise State and flipped to Washington during an official visit. His pledge to the Huskies lasted less than a week, though, as USC made a push prior to the dead period in an effort to add a quarterback to its recruiting class.

The prospect revealed the reasons for his decision.

"I'm ready to get in there and start competing," said Greene, who intends to enroll in time for spring practice. "There were other schools that were recruiting me, but I just wanted to focus on USC and Washington. Coach Sarkisian called me after he made the move and told me really wanted me. I'm excited because it's the same offense we ran in high school."

The 6-foot-2, 194-pound Greene, a three-star prospect, is rated No. 26 among dual-threat signal-callers in the 2014 class. He comes from a program that has been a pipeline for the Trojans in recent years, with receivers Robert Woods and Marqise Lee being the notable stars. USC is also in pursuit of teammate Adoree' Jackson, a five-star athlete who, along with Greene, watched the Trojans from the stands at the Royal Purple Las Vegas Bowl on Saturday, as well as UCLA receiver commit Jordan Lasley.

USC whiffed on No. 1-rated pocket passer Keller Chryst (Palo Alto, Calif./Palo Alto) in the summer when he committed to Stanford. Former interim head coach Ed Orgeron then made a run at Miami commit Brad Kaaya (West Hills, Calif./Chaminade) after taking over for Lane Kiffin, but the Elite 11 finalist said Saturday that he had not heard from the Trojans since Sarkisian arrived from Washington.

Last year, USC landed No. 2-rated pocket passer Max Browne (Sammamish, Wash./Skyline) but he redshirted this past season. The Trojans also hold a commitment from 2015 quarterback David Sills (Elkton, Md./Eastern Christian Academy), who made a much-publicized decision when he was only 13.

Greene passed for 2,544 yards and 33 touchdowns in his senior season. He also rushed for 1,209 yards and 14 scores as he helped Serra to an appearance in the divisional title game.

The decision gives the Trojans 15 commitments in the class. Greene became the fifth to commitment since Sarkisian was hired on Dec. 2.
