Oklahoma football: Sooners Kenny Stills, Tony Jefferson officially headed to NFL Draft

“We appreciate the contributions that Tony and Kenny have made during their time at Oklahoma,” Stoops said. “We wish them both the best as they pursue their opportunities in the NFL.”

ESPN ranks Jefferson (5-feet-11, 212 pounds) as the fifth-best safety in the 2013 drafft class, and the 82nd-best overall prospect. Stills (6-1, 190) is ranked as the 14th-best receiver and 73rd overall.

The Associated Press named Jefferson a second-team All-American this season; he led Oklahoma in tackles with 119 and intercepted two passes. He played most of the year with a high-ankle sprain suffered early in the season.

Stills was Oklahoma's leading receiver as a junior, catching 82 passes for 959 yards and 11 touchdowns. In what ultimately became his final college football game — a 41-13 Cotton Bowl loss to Texas A&M last Friday — Stills caught seven passes for 67 yards.

Stills caught 204 career passes over his freshman, sophomore and junior seasons, good for third all-time at Oklahoma. He's also just the fourth player in school history with at least 200 career receptions.

His father, Ken Stills, played safety in the NFL for six seasons.
