Campbell visited Louisville last Friday and got a chance to learn more about Charlie Strong's Cardinal program.
"I went on a tour of the school and sat down with Coach Strong and talked to him for a long while," Campbell said. "We talked a little about football, but we really talked on a personal level. He's a good guy. I like him a lot. It was a good visit. The people up there are great."
Before his visit to UofL, Campbell told Scout.com that Iowa and Tennessee were sitting at the top of his list of favorites. After visiting UofL, Campbell told InsideTheVille.com that the Cardinals were rising on his list.
"They're definitely higher on my list than they were [before the visit]," Campbell said. "I'm glad I went to see what it's all about. I always knew they had good facilities because a former player from there coached at my school last year and I knew they had good facilities. The city is [also] nice."
Campbell visited Kentucky before heading to Louisville for a final visit last week.
"Kentucky visit went well," Campbell said. "They have a great coach and both schools were good to visit. Now I have a really hard decision to make to see where I'm going to go."
Though Iowa remains at the top of his list, Campbell said Tennessee, where he visited last week, has fallen down his list of favorites.
"Iowa definitely is high on my list," Campbell said. "I can't say that about Tennessee any more. I just felt the right vibe at Iowa from the coaching staff."
Having visited four of his top five schools, Campbell now will travel north to check out Boston College. After that, Campbell could be prepared to make a college decision.
"I'm still fresh off the trips and I've got to get home and see what I am going to do," Campbell said.
