"I thought we signed a number of players that would have significant roles as freshmen for us," the head man said. "With injuries, that (role of freshmen) has become even more significant, especially with the receivers.
"There are a lot of (first-year) guys in there but that's good. It's good for the competition, and it shows these guys have worked really hard."
Just as Kiffin was not surprised by the number of rookies in key roles, he was not surprised that the No. 1 offense drove to a quick touchdown on its first possession of the scrimmage.
"I'd love to say it felt great but I understand it wasn't a live (full-scale) day and the defense wasn't throwing a ton of stuff at 'em," Kiffin noted. "So, I would've expected they'd score on every series with the setup today."
