"I committed probably about two and a half weeks ago," Frederick told InsideTheVille.com. "I'm really excited to go there."
Frederick, whose only other offer came from Blinn (TX) junior college, committed to the Cardinals without ever seeing the Louisville campus. Frederick said that he and four-star teammate RB Aundre Dean will make an official visit to Louisville this weekend.
"I was in Aundre's house when Coach Alford was talking to him and I was listening and he really caught my attention," Frederick said.
Frederick was a key member of Katy's 5A Texas state title team this season.
"He stuck out on a team of great athletes," said Texas Scout.com analyst Alan Zepeda. "He's a play-maker. He makes plays all over the field. He's very quick, has great instincts and makes a lot of tackles behind the line of scrimmage."
Frederick, a first team All-District selection after recording eight interceptions this season, said that he had received interest from Arizona State, Baylor and Wichita State.
"He's a good football player," Katy coach Gary Joseph said. "He's really improved in the last year and a half – he started for us as a junior but his strength and speed really increased his senior year. He made a lot of plays for us – made some interceptions. He's got great coverability. He's got long arms and he's very rangy. He's got a lot of upside."
Frederick holds a 2.9 GPA and says he's, "real close to gaining my eligibility. I've still got to get the test (score)." Academics, though, could be a problem for Frederick.
"(Louisville) told me they were going to place him in a junior college if he couldn't get in," Joseph said.
