The 6-foot-6, 340-pound Elam met with Charlie Strong, took a tour of the facilities and then was at the basketball game against Notre Dame.
"It was a great visit," Elam said.
Elam said the Cardinals had been in contact with his coaches but since the offer he's trying to build a better relationship with the coaches.
"They told me I am welcome any time, so I decided to come up," he said. "I really like Louisville and really likes the visit."
Elam said he was impressed with Strong.
"I love coach Strong," Elam said. "He's such a great person and a great coach. He's so down-to-earth and seems genuine. He's a great guy."
Elam said he is trying to "keep an open mind," and now has four offers – U of L, Kentucky, Western Kentucky and Alabama.
"Right now, I just don't know," he said.
