"It was great," he said of the trip. "I got to eat a lot, hung out with the players and coaches and got to know more about the Louisville program."
"The players there are great people and not just on the field," he continued. "The players and coaches are people of great character."
Virginia Tech in the Toyota Gator Bowl was a hit with those making weekend visits, including Walker.
"It was great to see how they conduct things on a day-to-day basis," he explained. "They move fast and are really motivated."
Walker, who made an official visit with Ole Miss in November, added that despite his strong visit with the Cardinal program, he is planning on making more trips prior to making a college decision.
"They would have liked to have heard that, but I want to take all of my visits first" he replied when asked if he was asked to commit during his stay in Louisville. "I'm going to South Carolina and Tennessee in January."
As a senior at Wynne (Ark.) High School, Walker recorded 64 tackles, 5 sacks and an interception, helping to lead his team to the Class AAAA state title.
