Crim, who is teamed up with Ocala (Fla.) Vanguard, checks in as the nation's 95th-ranked safety and 29th-ranked safety in the South.
"I'm comfortable with UCF," Crim said. "I talk to (defensive graduate assistant) coach (Jack) Cooper almost every day. They are a great fit for me.
"I'm trying to get this class going and make something happen by being the first commit."
Kolby Smith, a Sunshine State native himself who is in charge of grooming the running backs on Louisville's staff, broke the news by delivering the offer to Crim.
"I like their defense," Crim said. "They are always after the ball and high-paced. They like to send blitzes, which is the type of thing I like to do. They get players to the league that produce in the league very well.
"They want me to get down there and feel I would come in and make a big impact. They feel like their program is a great fit for me, and that they can get me to the league."
Crim needs to familiarize himself with coach Chris Ash's program, but says Rutgers envisions him hitting the field as early as his freshman year.
"I don't know much about Rutgers, but they like the way I play and want me to play safety and nickel," Crim said. "They want me to play a huge role in their defense.
"They don't just want me, but (defensive line) coach (Shane) Burnham says they need me on the defense."
Crim, 6-foot, 195 pounds, says he is making the journey down to Central Florida's campus on Saturday.
