Now that USC has wrapped up the first of two major practice sessions, beleaguered head coach Lane Kiffin may be left with more questions than answers.
After no less than 20 players were unable to participate in the spring game Saturday, the first of those questions posed is whether or not injuries have made any assessment of the roster premature.
Those injuries contributed to Kiffin's decision not to have his team tackle for Saturday's game and because of this, several units were unable to fully exhibit their capabilities.
Still, enough was shown to give the entire coaching staff a glimpse of what kind of team they can expect to field in 2013, and while there is plenty of reason for optimism, there are also an abundance of concerns.
For Kiffin, how he deals these worries will go a long way toward determining whether or not he will be invited back to coach the Trojans in 2013.
This slideshow will focus on five concerns Kiffin and his staff will take into the fall practice session.
If he can come up with solutions, USC can surprise people this year.
If not, well...
Note: List order is predicted on area of most concern
