A wide receiver for the Tennessee Titans. He played college football at the University of Southern California, where he was an All Pac-10 selection.

Williams attended high school at Springdale High School under head coach Gus Malzahn. During his senior year, he played wide receiver, running back and defensive back and earned accolades as an All-American, catching 63 passes for 1,495 yards with 24 touchdowns, running for 463 yards on 31 carries with 12 touchdowns and had eight kickoff returns for 254 yards with two touchdowns on offense, while also making 25 tackles and 3 interceptions (one for a touchdown) on defence despite missing several games with injuries. Springdale went 14-0 in 2005, won the Arkansas state championship and finished No. 2 nationally.

Williams initially planned on attending the University of Florida, but, in February 2006, switched to Arkansas, joining three other star teammates who had already committed.

Growing up in Springdale, Arkansas, Williams began his college career at nearby Arkansas, joining Springdale High School teammates and star recruits, quarterback Mitch Mustain, and tight end Ben Cleveland. Head coach Houston Nutt's Razorbacks football team had hired the trio's high school coach, Gus Malzahn, as his offensive coordinator a few months before signing day.[1] As a first-year freshman, Williams started 5 games for the Razorbacks and appeared in all 13 games, catching 19 passes for 235 yards and 2 touchdowns while ranking second in receptions on the team. He was honoured as a 2006 Sporting News Freshman Third-team All-American and Freshman All-SEC.

By the latter half of the 2006 season, the Razorbacks' offence had become run-oriented, behind star running back Darren McFadden. In mid-December, Williams' parents, along with those of two other freshmen, met with Arkansas athletic director Frank Broyles to raise concerns that their sons might not be a good fit for the Razorbacks' system when they had been used to a pass oriented, spread offence under Malzahn's tenure at Springdale. Soon after the meeting, Williams asked for a release to transfer to another school and it was granted; by early January 2007, he decided to transfer to USC, entering in the spring semester. Malzahn soon left to join the coaching staff at Tulsa and Mustain later joined his teammate at USC.
