Dale Dixson was back at defensive tackle Tuesday.
"I was a lot happier than I was yesterday," he said. "I was comfortable. Yesterday, I felt like a freshman. Today, I actually felt like a fifth-year senior."
Backup guard Zeb McKinzey, whose shoulder injury prompted Dixson's first position change, will not need surgery, Richt said. Still, it's too early to tell when McKinzey will be ready to play.
"It's got to cool down as far as the soreness, and I don't know how long that'll take to be honest with you," Richt said.
Dixson's move back to defense helped ease the mind of defensive line coach Rodney Garner, who, as usual, is displeased by the progress of his tackles.
"We aren't mentally tough," said Garner. "We have to find some guys who can play. That's the bottom line. We've got a long ways to go."
"I don't know who the No. 1s are," Garner said. "That's a good question. If you ask me today, there ain't none."
Freshmen tackles Ricardo Crawford and Geno Atkins "have to learn how to work at this level," Garner said. "They have to get away from the high school mentality and develop more of an SEC mentality," he said.
At least one of them will have to play this year, said Garner, who projects three or four of the true freshmen defensive linemen will see action this year. One of the freshmen ends – Brandon Wood, Kiante Tripp, Michael Lemon and Demarcus Dobbs – will have to be trained to play both end and tackle, Garner said.
