The area that appears to need the most attention, especially with depth is along the Cardinals defensive line, both at the tackle and end spots.
"We need to get another guy to be able to rotate and play in there," Petrino explained. "It will probably come either out of the true freshmen, possibly Adrian Grady, or [junior] Elvis Dumervil could rotate in there."
With All-Conference selection Marcus Jones having a firm hold on one defensive end spot, the other spot, as well as much needed depth, continues to be a question.
"We've got to have depth there so we can keep them fresh," said Petrino. "Elvis right now would be at the other spot as the starter if we were to start today and then Chad Rimpsey. We'll probably have to rely on some young guys there too. Brandon Cox and maybe Breno Giacomini...that's the position where we're going to have to have some depth provided by true freshmen."
Petrino also mentioned an incoming freshman linebacker that may see action.
"We've got a young kid coming in, Lamar Myles, that I'm really looking forward to seeing," continued Petrino. "He was an outstanding high school player and is extremely fast. He probably had a couple of the best hits that I've seen from anybody on video that we recruited. So, we'll see how quick he can get into it."
The second-year head coach also spoke highly of the Cardinals secondary and commented on the criticism that the unit received following the 2003 season.
"I feel like they took the brunt of the criticism from last year, like the offensive line did two years ago," Petrino said. "If things don't as well as you would like, one group seems to get some of the blame that's not deserving. We have to have a pass rush."
