Kragthorpe, along with linebackers coach Reggie Johnson, visited with the 6-foot-2, 220-pound four-star prospect on Monday night.
"It went real good," said Bynes. "I thought he was pretty cool. He seems like a good coach and I think he'll do a good job at Louisville."
"They've all been here now," said Bynes, who will make an official visit with South Carolina this weekend. "It makes you feel like you are really wanted. The head coach doesn't visit everybody, so it feels good to know that they want you to come play for them that much."
Bynes is planning to announce his college choice at his school on national signing day on February 7.
"That's going to be real tough," he explained. "When I take my visits I look at everything. Even the little things. Part of it will be if I think a school can help me get to the next level or not and I think that all of the four that I'm looking at can."
