Spring Football Guide from the official USC site.
Of note:
Offense
*Sanchez had three starts last year (Arizona, Notre Dame, Oregon) and went 69-114 (60.5%) for 695 yards with 7 TDs and 5 Ints on the year (I like the five interceptions).
*Deep, young, talented pool of running backs. Someone who follows USC closely can try and explain how they think this jumble will work out if they feel like it.
*Both starting WRs return, but they accounted for less than half of the teams receptions in 2007. They will need to step up their production in 2008, especially since...
*Fred Davis is gone at TE, and the guys looking to replace him have a combined total of 5 career receptions.
*Only OG-C Jeff Byers returns as a starter on the offensive line. However, several returning players have starts under their belts, although not many. They are: OT Butch Lewis with 3 career starts, C Kris O'Dowd (remember him?) also with 3 career starts, OG Zach Heberer with 2 career starts, and OT Charles Brown with 1 career start.
Defense
*USC needs to replace two of the "best defensive lineman in school history" (sounds good to me) in Sedrick Ellis and Lawrence Jackson. The other two starters return, will be seniors, and are described as "steady".
*Linebacking corp in good hands with Maualuga and Cushing. Clearly will be a strength of the defense, along with...
*The defensive backfield looks to be another strength for the Trojans, which Carroll describes as "maybe the best since I've been at USC" (must be all those #1 guys Petey recruited). They do have to replace "lockdown" corner Terrell Thomas who had eight career interceptions.
*USC needs to find a new long snapper and holder. They are looking to improve special teams play from last year.
Lots more good stuff in that pdf file I linked if anyone wants to look at it.
