Okay, so it was more like no pads, no helmets, no cleats for the Trojans' Thursday practice.
"Everyday we're looking at our team and where we are at," Kiffin explained. "After yesterday everybody was really tired. I think the price we've paid with the numbers where we're at plus the injuries, I think has taken a toll on our front line guys.
"The last thing we want to do is run them into the ground. Especially our defensive guys who will be playing a lot of plays on Saturday."
Just the second game into the season, and it's already the Pac-12 opener for both USC (1-0) and their Washington State (0-1) opponent.
"[He] really had a great game the other night," Kiffin said of Halliday. "Really accurate, very poised in the pocket, didn't let the rush get to him and kept his eyes downfield. I thought he played really well."
The Trojans' defensive line, who collected seven sacks against Hawaii quarterback Taylor Graham, will need to be equally aggressive in their pursuit of Halliday in order to get the Cougar scrambling. USC will most likely play in their nickel package most of the game in order to defend the volume of passes expected.
