Candidates to replace receivers coach John Morton

Tuesday's announcement that passing game coordinator and receivers coach John Morton accepted a job with Jim Harbaugh and the NFL's San Francisco 49ers is the first coaching switch for USC this offseason.

Who could Lane Kiffin and the Trojans appoint to replace him?

It would seem that graduate assistant Keary Colbert is the likely candidate. Colbert, a former USC receiver who also spent six seasons in the NFL, worked with the tight ends this past season and earned praise from Kiffin at various points in the season.

Another option could be longtime college and NFL assistant Kippy Brown, who currently coaches receivers for the NFL's Seattle Seahawks. Former USC coach Pete Carroll is the Seahawks' head coach, of course, and it is unlikely Brown would jump down a level to work under Kiffin at USC. But Carroll today fired offensive coordinator Jeremy Bates (remember him, USC fans?) and could be in the process of revamping his offensive staff.

Brown was hired to Kiffin's staff at Tennessee in December 2009 and was named the Volunteers' interim head coach when Kiffin departed for USC in January 2010 but left for the Seahawks when he was leapfrogged by Derek Dooley for the head coaching job.

In a statement released Tuesday by USC, Kiffin said he has not yet determined who will fill the receivers coach position for the 2011 season.
