Sources: Oklahoma set to finalize deal to hire Clemson DC Brent Venables as football coach

Oklahoma officials are scheduled to arrive in Clemson, South Carolina, later Sunday afternoon to finalize a deal with Clemson defensive coordinator Brent Venables to become the Sooners' next football coach, sources told ESPN.

Venables has been a major part of Clemson's championship run under Dabo Swinney and has a long history at Oklahoma. He was on the Sooners' staff from 1999 to 2011, serving as co-defensive coordinator from 1999 to 2003 and defensive coordinator from 2004 to 2011.

While at Clemson, Venables was the Broyles Award winner in 2016 as the top assistant coach in college football. He has turned down multiple head-coaching opportunities in recent years to stay at Clemson.

Venables, whose defenses at Clemson have consistently ranked near the top nationally in most statistical categories, is the highest-paid assistant coach in college football. He received a contract extension prior to this season that took him to $2.5 million annually. That's after turning down the Auburn head-coaching job a few months earlier.

If a deal is reached with Venables at Oklahoma, sources told ESPN that Ole Miss offensive coordinator Jeff Lebby would be his top choice as offensive coordinator. Lebby, a semifinalist for the Broyles Award each of the past two seasons, spent four years as a student assistant at Oklahoma after signing to play there before suffering a career-ending injury.
