Two weeks ago, the Houston Texans reportedly had interest in Cory Undlin to be their defensive coordinator. Undlin is the 49ers passing game specialist and secondary coach. He also has experience as a defensive coordinator with the Detroit Lions.
Houston ended up hiring Matt Burke as their defensive coordinator, but that interview may have been to see whether Undlin would take on another role for the Texans. Sure enough, according to Aaron Wilson, the DeMeco Ryans and the Texans are expected to hire Undlin as their defensive passing game coordinator.
