Garret Greenfield Bio
Garret Greenfield is an American former professional football player who played the offensive tackle position. Born on September 20, 1999, in Sioux Center, Iowa, he built a decorated college career with the South Dakota State Jackrabbits before reaching the National Football League as an undrafted free agent. He is a two-time Football Championship Subdivision national champion and a three-time First-Team FCS All-American. Greenfield later retired from professional football in July 2025 after stints with three NFL organizations.
Early Life and Background
Garret Greenfield grew up in Rock Valley, Iowa, a small community in the northwestern part of the state. He attended Rock Valley High School, where he was a multi-sport athlete in football, basketball, and baseball. On the gridiron, he lined up on both the offensive line and the defensive line, earning recognition as his team’s most valuable offensive lineman on two occasions.
During his prep career, Greenfield helped Rock Valley capture a state championship in 2016 and return to the semifinals the following year in 2017. His combination of size and athleticism drew attention from college programs, and he ultimately committed to continue his football career at South Dakota State University.
Path to American Football
Greenfield joined the South Dakota State Jackrabbits and began his collegiate career in 2018 as a true freshman. He appeared in three games during that initial season while preserving a year of eligibility by redshirting. The following year, he played in seven games and continued to develop his technique on the offensive line.
When the spring 2021 schedule arrived, postponed from 2020 due to the COVID-19 pandemic, Greenfield stepped into a starting role. He started all ten games that spring, helping South Dakota State reach its first-ever national championship game and earning First-Team All-American recognition from multiple selectors. His emergence as a reliable starter set the stage for the most decorated stretch of his college career.

Early Career (2018–2021)
As he adjusted to the college level, Greenfield spent his first two seasons in a developmental role while learning the Jackrabbits’ offensive system.

The spring 2021 season marked his arrival as a full-time starter and the moment he became a cornerstone of the offensive line.
Starting every game that spring, Greenfield anchored a unit that pushed South Dakota State to its first national championship appearance. His performances during that stretch earned First-Team All-American honors and signaled to NFL scouts that he possessed the tools to play at the next level.

South Dakota State captured its first FCS national championship in 2022, and Greenfield was named a First-Team All-American for the second time in his career.
He returned for a final college season in 2023 and won a second consecutive national championship while starting all fifteen games, collecting another First-Team All-American selection. Over his final three seasons, he earned First-Team All-Missouri Valley Football Conference honors each year and finished his career as one of the most accomplished offensive linemen in program history.
