Barron is one of seven returnees with extensive playing experience; all five starters from 2003 are back.
"Everybody knows that each other person is going to be accountable for his actions and get the job done," he said.
"You get a feel for tendencies after a while."
The 6-6 320-pounder from South Carolina is also the only member of the unit that has remained injury-free during the pre-season. All four of the other projected starters have missed practice sessions while nursing various minor ailments.
"It'll be nice to be back at full strength," he said. "We have a lot of experience coming back on the line but if guys are hurt that doesn't mean anything."
Barron said blocking for an explosive back (or pair of backs) makes the hard work easier.
"It's always exciting to have a great back behind you," he said.
"That's something that I've had every year I've been here. With Greg Jones back there, you knew you had to clear a big hole. Now with Leon and Lorenzo back there, we have two great backs that can make people miss."
