With 50 days until national signing day, there is still plenty left undecided in the Pac-12. Five of the top six West region prospects -- as well as seven more ESPN 300 prospects -- remain uncommitted and have significant Pac-12 interest. There also figures to be a battle for the top class in the conference, as at least six schools will jostle for position.
Here are 10 Pac-12 storylines that could help shape signing day for the conference.
1. Who are USC's assistant coaches?
At this point, very few questions about USC's coaching staff are answered. Steve Sarkisian is in place as the head coach and has retained wide receivers coach and ace recruiter Tee Martin. Making the trip down from Washington with Sarkisian are linebackers coach and recruiting coordinator Peter Sirmon, defensive backs coach Keith Heyward and assistant coach Johnny Nansen, whose position hasn't been determined. USC assistants Clancy Pendergast, Clay Helton, Mike Summers and John Baxter are among the candidates to stay at the school, but nothing is likely to be announced until after USC's bowl game. Who winds up filling out that staff will be on the minds of a number of top prospects, especially if the coaches come from other Pac-12 programs.
