Not that USC's second-year coach isn't looking forward to the remaining eight workouts.
It's just that August will bring two dozen new players to go along with more than a dozen who have been sidelined or limited this spring because of injuries.
"Right now, we would not be a very good team if we were playing," Kiffin said after Tuesday's practice. "We have some really good players but we wouldn't be able to put it together."
Kiffin said the Trojans have some "legitimate, NFL, star players," including receiver Robert Woods, quarterback Matt Barkley, tight end Rhett Ellison, defensive end Nick Perry, cornerbacks Nickell Robey and Tony Burnett and safety T.J. McDonald.
But Kiffin lamented a gap between those players and other starters.
"Our challenge is to develop those guys," he said.
Defensive tackle Christian Tupou (knee) and Wes Horton (foot) participated in team drills for the first time, but Tupou's day was cut short after a collision with another player. Tupou sat out the rest of practice and was scheduled to have X-rays, Kiffin said.
Tupou redshirted last season and is expected to help make up for the loss of Jurrell Casey, who made himself available for the NFL draft.
"He spent a year with me last year and was almost a coach on the field," defensive line coach Ed Orgeron said of the fifth-year senior. "He understands the game a little bit better, but you've got to get out there and do it."
Redshirt freshman cornerback Patrick Hall intercepted two passes, including one thrown by Barkley. "Some are his fault, some aren't," Kiffin said of Barkley's interceptions this spring.
