Regarded as one of the nation's premier shutdown pass defenders, Jenkins teamed with Trae Williams to give the Bulls an outstanding cornerback combination.
Along with free safety Nate Allen and strong safety Carlton Williams, South Florida's secondary combined for 131 starts at USF.
The Bulls ranked eighth in the nation in passing efficiency defense (105.27 rating) in 2007 after ranking 11th nationally in 2006 (104.26) and 16th (109.38) in 2005, thanks largely to the performance of their right cornerback. Jenkins improved his draft stock, showing professional scouts that his blazing speed could also be used as a kickoff returner. On the first kickoff return for 2007, he set a school record with a 100-yard touchdown return vs. Cincinnati.
Jenkins was a standout safety at Bradenton Southeast High School, earning Super Prep All-American honors. He was rated the 27th player in Florida by the Orlando Sentinel's Bill Buchalter, and he was named first-team All-Gridiron by Sean Alveshire (FloridaKids.net), who picks the top players in the state regardless of their school's classification.
The first-team Class 3A All-State choice, Jenkins was selected by the Sarasota Herald Tribune as its Defensive Player of the Year. He was the District Player of the Year in 2002 after he recorded 42 tackles, two interceptions, one caused fumble, one fumble recovery, two blocked punts and two blocked field goals. He also played running back and led the team with 859 yards and 11 touchdowns that year.
Jenkins was heavily recruited by Florida, Florida State and Louisiana State, but decided to enroll at South Florida in 2004. He started three of the team's first four games at left cornerback, including the season opener vs. Tennessee Tech, but an ankle sprain forced him to sit out vs. Army and kept him from returning to the starting lineup for the rest of the year. He finished his first season with 27 tackles (19 solo), two forced fumbles and nine pass deflections. He also blocked a punt that he returned four yards.
In 2005, Jenkins shifted to right cornerback, starting all 12 games. He earned All-Big East Conference second-team honors, as he produced 38 tackles (33 solo) with a stop for a loss and two forced fumbles. He returned a punt 27 yards, intercepted two passes and broke up five others.
Jenkins had a sub-par junior campaign, starting the first 12 games at right cornerback, but played as a reserve vs. East Carolina in the Papajohns.com Bowl. He made just 27 tackles (18 solo) with a forced fumble, a fumble recovery and an interception. He batted away fifteen passes and gained 27 yards on two kickoff returns.
During 2007 spring camp, Jenkins was arrested for misdemeanor charges of disorderly conduct and resisting arrest without violence after a fight erupted outside a bar he was attending a party for former USF linebacker Stephen Nicholas. Despite not being violent, police used a taser Jenkins and he was briefly suspended from the team.
He returned for fall camp, reclaiming his right cornerback spot, and went on to earn All-American and All-Big East Conference first-team honors. He recorded a career-high 41 tackles (31 solo) with four stops for losses. He intercepted three passes, deflected 12 others and averaged 30.4 yards on seven kickoff returns, including one touchdown.
In 48 games at South Florida, Jenkins started 40 contests, including 37 at right cornerback. He registered 133 tackles (101 solo) with six stops for losses of 26 yards and one quarterback pressure. He caused five fumbles and recovered another. He also broke up 41 passes and had six interceptions for 41 yards in returns. He gained 240 yards with a score on nine kickoff returns (26.7-yard average) and 31 yards on two punt returns, as he also blocked one kick.
