Lane Kiffin revealed the Radiers' depth chart on Tuesday and there is a three-way tie on the first team between Daunte Culpepper, Josh McCown and Andrew Walter. Kiffin then said he has an idea which quarterback will start Saturday's exhibition opener against the visiting Arizona Cardinals, but that everyone must wait until today before he makes an announcement. "No one of the three has emerged as the clear-cut guy by any means," Kiffin said after Tuesday's single practice in Napa. "We don't need to have a starter right now. We're going to let them play and do the best that we can." Kiffin seemed to rule out Culpepper by saying he'd have a "limited package." Culpepper joined the team last week and is still learning the playbook and terminology.
