Hicks, the son of Kimilar and Ronnie Graham, grew up in Hot Springs, Arkansas and attended Hot Springs High School. While there he took part in high jump and hurdling. He was a 15-time state high school champion and the 1999 American junior champion in the high jump. He attended the University of Mississippi and competed for their Ole Miss Rebels collegiate team from 2002 to 2004. In addition to his NCAA indoor titles, he ran a school record 7.61 seconds for the 60 m hurdles. Outdoors, he was fifth in the NCAA 110 m hurdles in his freshman year and was runner-up at the 2004 Southeastern Conference Championships.[3]
Hicks never competed on the global stage as a senior athlete, despite ranking near the top ten in the world in the period from 2008 to 2013.[4] He was a prominent athlete on the professional track circuit, however, and won the Bislett Games during the 2009 IAAF Golden League season.[7] He ranked seventh at the 2009 IAAF World Athletics Final.[8]
He opted to run for Nigeria late in his career.[9] Another American hurdler, Tyron Akins, opted to do the same around this period in 2014.[10]
