The 5-foot-11, 190-pound Cox has already attended a couple of junior days this spring.
"I went to junior days at Texas A&M and Oklahoma," Cox said. "At Oklahoma I talked to coach Veneables and it was real cool. I had a really good time there."
As a junior Cox collected 81 tackles, two interceptions and forced three fumbles.
"Oklahoma and Louisville are my top two," Cox said. "I am looking for a program with a winning tradition and where I will get a good education."
Cox earned first team all-district honors last fall.
