Three former Oklahoma players and Arizona's former secondary coach have joined the Sooners coaching staff.

Joe Jon Finley (offensive quality control), Derrick Strait (defensive quality control), Joey Halzle (offensive graduate assistant) and Ryan Walters (defensive graduate assistant) are the newest additions to the OU staff, it was announced on the Sooners' official Twitter feed today.

Finley was a two-time honorable mention All-Big 12 tight end at OU from 2004-2007.

Strait, a consensus All-American cornerback as a senior at OU, won the Nagurski (best defensive player) and Thorpe (best defensive back) Awards in 2003. He was also named Big 12 Conference Defensive Newcomer of the Year in Oklahoma's 2000 National Championship season.

Halzle, a junior college transfer quarterback, backed up Heisman-winner Sam Bradford from 2006-2008 for the Sooners.

Walters comes to OU after serving as the secondary coach for Arizona in 2011 under Mike Stoops. He was the youngest football assistant coach in the Pac-12 Conference. He started 33-games at Colorado before joining the Arizona staff in 2010 as the defensive graduate assistant.
