USC football mailbag: Have the Trojans’ practices changed?

Spring football practice is officially in swing at USC.
The Trojans held their first workout Tuesday and were to return to Howard Jones Field on Thursday afternoon.
There is no shortage of storylines, from Clay Helton recasting himself as a disciplinarian, to intrigue surrounding new offensive coordinator Graham Harrell and a possible quarterback competition. The next month should be interesting.
