The 6-foot-1, 215-pound linebacker was a guest of the program for U of L's victory over South Florida last season, an experience that he described as feeling "like home."
Attending Junior Day allowed Graham an opportunity to learn more about what Louisville has to offer and build a stronger relationship with the Cardinals coaching staff.
"We went to the basketball game against Seton Hall and then we came back and talked about how they run things and about the school," he said.
While he was somewhat familiar with U of L prior to the weekend visit, Graham left Junior Day even more impressed.
"It went really well," he said. "I learned a lot more about the coaches and about Louisville itself. I ended up liking it more than I thought I would."
Joined by his teammate Jalen McIntyre on the visit, Graham plans to return to Louisville again for the Spring Game on April 13.
Graham is also receiving interest from Bowling Green, Indiana, Iowa, Louisville, Missouri, Purdue, Vanderbilt and Wisconsin
