"He was one of the top receivers in the country," Chizik said. "He was a great player. You talk about your staff going out and finding guys, wherever they're at. There are different circumstances with all these guys out here. That's one of the things I keep bragging about with our guys.
"He's one that we found," he added. "It looks like he could step in and play today physically. He hasn't taken a step back. He's a couple of years older and probably a couple of years wiser. I think mentally and physically he's ready to play football again."
Benton, who played his high school football at Bastrop High, had previously signed twice with LSU, but did not qualified to enroll for the 2008 season. He has been out of football for a year working on becoming an academic qualifier.
At 6-2, 185 pounds with good speed, he is known for running good pass routes and is a deep threat.
He took an official visit to Auburn in January.
A three-year starter and an All-State player in high school, he caught five passes for 115 yards and a touchdown in his team's state championship victory over Breaux Bridge his junior year. He caught 41 passes for 805 yards and 11 touchdowns that season.
As a senior in 2006, Benton finished the year with 1,037 receiving yards.
