He hasn't played OT in the pros yet, but he did play a lot of games at Tackle in college:
Ronald Leary bio
As a redshirt freshman (at Memphis), he was a backup for the left and right tackle positions. The next year he was named the starter at left tackle, where he would remain for the most part of his college career, while making 36 consecutive starts.
During his senior season, he underwent surgery in May 2011 to repair a torn meniscus in his left knee, but didn't miss any games. He ended protecting three different quarterbacks, while starting the first six games at left tackle, before switching to right guard when injuries impacted the offensive line. He was named second-team All-Conference USA and shared team MVP honors with Dontari Poe.
