"Those are the four that I am really looking at," said Bynes, who remains open for his final official visit. "I'm not really sure about my last visit."
Bynes, who is rated as the nation's fifth strong-side linebacker by Scout.com, talked with InsideTheVille.com about each of his favorites.
Iowa: "It was a great atmosphere up there. There's just something about Iowa that I like. My visit there was amazing. They have great facilities."
Auburn: "I went there for a camp and got to know the coaches. They have really great facilities and they make sure that you are taking care of your academics before anything else."
South Carolina: "They play a lot of young players and they have one of the best coaches in Steve Spurrier."
Louisville: "They have a great offense, but the defense needs some more fire power. It's a good program that I feel that I could go to and hopefully make a difference."
While Bynes has yet to schedule a date to visit Louisville, U of L assistant coach Reggie Johnson is scheduled to visit with him this week and will likely set a date for the trip during the in-home visit.
"I talked to Louisville a week or two ago," he said. "Coach Johnson is coming by to see me on Thursday."
Bynes, who had his senior season came to an early end when he sprained his MCL late in the season, reports that his knee is close to returning to full strength.
"It's great," he said. "I'm so happy now. Right now I'm just working in the weight room to get my strength back."
Playing in just nine games this season, Bynes totaled over 100 tackles, 3 forced fumbles, 3 recoveries and three sacks. As a junior he earned 1st Team All-County after recording 147 tackles, eight forced fumbles, five recoveries and two sacks.
