Restivo's hard work on the recruiting trail resulted in Louisville's first '14 commitment this week when the 6'3, 278 pound Valentine verbally committed to Charlie Strong's program.
"It's really simple, Louisville has been showing a lot of love lately," Valentine said. "I like the way they treat you and how trustworthy they are. They've been stepping up and talking to me a lot. They were the school I really felt comfortable with. I'm going to take visits to other schools, too, but my first visit is going to be Louisville."
Valentine said Restivo, a first year assistant for the Cardinals, recently came down to Florida to watch him practice.
"We've been talking [a lot]," Valentine said. "He came down and watched me practice. I talked to him a lot on Facebook and he's a really cool guy to talk to. I have a lot of trust in him."
Strong has landed several elite Florida prospects in three years at Louisville, including quarterback Teddy Bridgewater, safety Gerod Holliman, defensive lineman B.J. Dubose and linebacker Keith Brown. Valentine said he wants to be Louisville's star recruit in 2014.
"It's a good program now," Valentine said. "A lot of big-time players from the 2013 class are going there and I want to help build it up. A lot of big-time recruits want to go to Alabama, LSU or Auburn, but I want to be one of the top 2014 players that go to Louisville."
Valentine, who plans to visit Louisville in June, recorded 80 tackles, 12 sacks and 22 tackles for loss last season. He runs a 4.7 forty and the Cardinals believe he'll be an athletic defensive tackle or end once he arrives on campus.
"I like to bull rush and have good speed off the ball," said Valentine. "I play tackle and defensive end. [Louisville] said they're going to use me at defensive tackle and end. They like my speed and how I come off the line."
Though Valentine plans to visit other schools he appears sold on the Cardinals.
"My [commitment] is very solid," Valentine said. "I plan to stick with it until I graduate from Louisville."
"In June, I'm going to take visits to Louisville and Florida and visit Miami, USF, Auburn and maybe Alabama in July."
