He sat out his sophomore season of football, instead serving in World War I as a gunnery sergeant in the United States Marine Corps.

After graduating from college in 1921, Boynton took a job at Bethlehem Steel, located in Steelton, Pennsylvania.

Boynton played just three games for the Jeffs that season but still scored two touchdowns, eight extra points and a field goal.

His return though sparked a dispute between Lyons and the new owners of the Buffalo Bisons; both parties claimed to have signed Boynton for the 1924 season.

During that game Badgers' quarterback Red Dunn broke through the line and headed downfield with Boynton in pursuit.

In 1926 he returned to Texas, and helped form the Southwest Officials Association and served as the organization first president.

After retiring from officiating, Boynton began a broadcasting career, where he provided radio commentary for several years.

During World War II, Boynton served as a lieutenant commander in the United States Navy Reserve.

Rochester manager, Leo Lyons, called Boynton the second greatest football player of the era, second only to Jim Thorpe.
