[1] During the beginning of his career, Mayberry played several positions along the offensive line before settling in at right guard for the majority of his tenure.

His solid play was recognized with a bid to the Pro Bowl after the 2002 season.

At Texas A&M University Kingsville, Mayberry was a consensus Division II All-America selection and a two-time All-Lone Star Conference pick at left tackle.

This can partially be contributed to a condition Mayberry developed as a child, as he has amblyopia in one eye.
