“I’m loving the vibe so far,” Mullen said in a video he posted from his visit. “Team feels like a family. Coach (Eric) Morris is awesome. All the position coaches are awesome. It feels like a family here.”

Along with his offers to OSU and Houston, Mullen has offers to TCU, Baylor, Kansas State and others.

The Cowboys moved quickly with Mullen. Offensive line coach Cody Crill extended an offer on May 5 before quickly setting up an official visit and getting him committed in early June.

He hails from Troy, Texas, a city of about 3,500 south of Waco. Like many of the athletes Morris recruits, Mullen is a multi-sport athlete, also throwing shot and discus. He has a 140-11 discus throw and a 42-7 shot throw this year, according to MileSplit.

Mullen is the fifth commitment in the Cowboys’ 2027 class and the first offensive lineman of the group.
