"I signed with Louisville," McCray said Wednesday morning. "I liked it down there. I liked the classroom size because I get more individual attention."
McCray said he had not contacted the Louisville coaches before signing his LOI, but planned to speak with the Cardinals coaching staff later in the day.
"I think they knew this weekend I was coming there but I don't think they knew for sure," McCray said. "I'll call them later and talk to them."
McCray needs to take a night school course to make up one credit to attain college eligibility but said that won't affect his scholarship to Louisville.
"It won't affect anything. It's just like a regular class but it's at night," said McCray.
McCray rushed for 1,535 yards and 18 touchdowns as a senior, while making 11 sacks from his outside linebacker position on defense.
The 6-foot-2, 210-pound running back chose Louisville over Marshall and Old Dominion.
