Just because USC has a bye this week doesn't mean the Trojans didn't play.
And an early-morning, 56-play scrimmage Friday probably won't help hush the folks who keep wondering why No. 3 quarterback Mitch Mustain hasn't been given a chance to play.
Mustain completed 10 of 12 passes for 141 yards with a pair of TD passes during the workout.
The big news is one touchdown pass went to receiver Ronald Johnson, who is seeing his first action since breaking his collarbone during the preseason.
That indicates that the Trojans best downfield threat should play at Notre Dame on Oct. 17, though the scrimmage didn't feature live tackling and the players weren't in full pads.
Other highlights of the scrimmage included freshman cornerback Torin Harris returning an interception 100 yards for a score. Harris also blocked a field goal, returned a kickoff 45 yards and had two tackles
The scrimmage was conducted at dawn so USC’s coaches could spend the rest of the day and weekend on the road recruiting.
