Robinson moved sophomore Jerry Franklin to middle linebacker and put him on the first unit in place of senior Wendel Davis. True freshman Terrell Williams slid into the first-team linebacker spot vacated by Franklin. Junior Rudell Crim has jumped ahead of sophomore Greg Gatson for one of the first-team cornerback positions.
Junior Jerell Norton, a former cornerback, is lining up with the first team at free safety this week, ahead of senior Matt Harris. Junior defensive end Jake Bequette took snaps with the first team ahead of junior Damario Ambrose.
With these players in starting positions during Wednesday's workout, Robinson said defensive coaches didn't have to urge the Razorbacks to get aggressive, like they did earlier this week.
"We are making sure we have guys that will tackle," Robinson said. "That's the bottom line. After our last scrimmage, we had to evaluate guys who showed courage, who ran at full speed to the ball. They might not necessarily be the ones who are right all the time, but they are doing some good things, and we can go from there."
• Sophomore receiver Joe Adams was missing during the first 20 minutes of practice and wasn't present as the Razorbacks jogged back to their locker room. No explanation was given for Adams' absence, as Robinson was the only coach to speak with the media.
Adams is expected to play a big role within the Razorbacks' wide receiving corps this season.
• Bobby Petrino Live made its debut Wednesday night from the Catfish Hole, hosted by Chuck Barrett, play-by-play broadcaster for Arkansas football and baseball. Arkansas coach Bobby Petrino, senior running back Michael Smith and Bequette joined Barrett and an enthusiastic crowd at the popular Fayetteville restaurant.
It was the first of 13 weekly, one-hour shows this year. Petrino, Smith and Bequette took questions from Barrett, the audience and from online submissions.
• London Crawford looked better Wednesday after returning to practice a day earlier. The senior receiver missed much of the week prior to Tuesday with a leg injury. Crawford limped noticeably after Tuesday's practice, but he didn't after Wednesday's workout.
• Junior offensive tackle Ray Dominguez appeared to be back with the first-team line during the first 20 minutes of practice, in place of sophomore Grant Freeman.
Robinson used the same word several different times during his meeting with the media following Wednesday's practice. It's a word his Razorbacks defenders have heard often from their defensive coordinator.
"I couldn't tell use how many times I've heard the word ‘courage' from him," Crim said. "He says it so much. He says that if you don't have courage, you can't play defense."
When talking about reasons for putting new players on his first-team defense, Robinson didn't shy from implying the Hogs had to get tougher.
"Football's about contact," Robinson said. "But if you don't display courage every single down, if you try to avoid a block or avoid a tackle, or try to do whatever you can to not get yourself dirty or not get a boo-boo on yourself, then let's move on (to the next guy).
"Let's be physical, that's what this thing is all about."
Robinson said he wanted "guys who are physical and who will throw themselves around." He also said players such as Davis, Gatson and Harris had plenty of time to climb back up Robinson's pecking order, as long as they showed the needed bravery.
"These changes are temporary," Robinson said. "We still have a long time to get our depth chart set. The moves we make in practices aren't permanent. Starters are fighting back and earning their positions back. We are going to establish courage, execution and full speed to the ball."
