So, the 6-foot, 185-pound Cooper made the call right away.
"I had a lot of good options," Cooper said. "Louisville said they wanted to talk to my high school coach and check out my transcript and then they offered. I had a good time on my visit (last month) there and the town and campus were great.
"The fans are amazing. Everything is good about Louisville."
Cooper said U of L fans could thanks Lexington Catholic quarterback Kyle Bolin, a U of L commitment, for helping bring him into the program. Bolin connected with Cooper on twitter and told the staff about him.
"After he told them, the coaches started emailing me and talking on Facebook," Cooper said. "It was pretty cool how I met him on twitter. We now text all the time and we have talked a lot. We have a good relationship.
"And that's good because he's the quarterback."
Cooper has another connection to Louisville. His first cousin, Shamar Johnson, is also committed to the Cardinals. He's a lineman who now lives in Pensacola, Fla.
The two cousins grew up in New Haven, Conn., but have remained in contact after moving to different cities with their families.
"I haven't seen him for a while because he lives in Florida, but we text all the time," Cooper said. "We're going to a family reunion this year."
And when asked if there would be a lot of red and black at the reunion, Cooper chuckled and answered, "Oh, yes."
"He told me Louisville was a great place to be and they had the best fans in the world and campus was pretty," Cooper said. "He said it was the right choice and that he really loved the coaching staff."
Cooper said he connected with Charlie Strong and also wide receiver coach Ron Dugans during his recruitment and also during his recent visit.
"I really like coach Dugans a lot," he said. "We spent like 30 minutes one on one time speaking about life and was a really good time talking with him. That's whom I will spend most of my time with in college. All the position drills and team meetings and all of that for the next three or four years.
"My family loved coach Strong when I visited Louisville. We talked a good 45 minutes with coach Strong, coach Dugans and coach (Brian) Jean-Mary. We all just sort of connected and that was nice.
"It's been kind of different (being committed) but it's a lot of fun. I still have friends who say, you are not signed yet and you are just committed until February. But it's cool and it's fun. I really like Louisville."
Cooper spends a lot of time on twitter, noting "it's a really cool social media place," and has met a lot of friends. But he's also been spending a lot of time working on his game to make sure he's better for his senior season.
"My strengths are that I am a deep threat," he said. "I stretch the field a lot and get past the corner," he said. "But my weaknesses are that I need to become better with my speed and quickness and do my route running better. I can get better."
Cooper had also been looking at Kentucky, East Carolina, Illinois, Miami, North Carolina, South Carolina and North Carolina State.
He's a three-star prospect for Scout.com. Over the past two seasons, Cooper has over 1,200 yards receiving and 15 touchdowns.
