Now, the 6-foot-3, 275-pound Willis calls the Cardinals one of his top three schools in the recruiting process.
"It was great again," Willis said. "I had a lot of fun watching them warm up and then go at it on the field against each other.
"I can't wait to go back. Louisville is ranked in the top three schools for me."
Willis has an offer from Indiana and has also been to Bloomington, Ind., multiple times. He's also visited Illinois, Purdue and Wisconsin and is hearing from Iowa, Northwestern and Cincinnati among several others.
As a junior, Willis helped Lawrence Central to an undefeated season and Class 5-A state title. He played mostly offensive line during his junior season but is mainly being recruited on defense by colleges.
