He was selected by the New York Giants in the second round of the 2007 NFL draft, and was also a member of the Philadelphia Eagles, St. Louis Rams, and Tampa Bay Buccaneers.

His career yardage record was surpassed by Canyon High School Wide Receiver, Drew Wolitarsky on October 5, 2012.

He played in the 2003 U.S. Army All-American Bowl with several of his USC Trojan teammates including Reggie Bush, LenDale White, and Sam Baker.

He also played high school basketball and was a teammate with former Los Angeles Lakers point guard Jordan Farmar.

Smith attended the University of Southern California, where he was one of the top two wide receivers by yardage for the USC Trojans football team.

Smith caught three touchdown passes from Heisman Trophy winner Matt Leinart in USC's 55-19 national championship/Orange Bowl victory over Oklahoma.

However, after returning from a shoulder and hamstring injury, Smith turned in an outstanding postseason as he became a reliable third down receiver for quarterback Eli Manning.

He made two big catches at the end of the first half in Dallas, which set up a game-tying touchdown and caught five passes in Super Bowl XLII, including four on third down.
