[1] As a junior, he posted 6 receptions (tied for second on the team with future NFL player Jimmy Burson) for 74 yards and no touchdowns.
In 1963, he gained 25 lbs (from 205 to 230) and started 6 games, while replacing the injured Lee Roy Jordan and Harold Hays.
In 1964, he began the season as the starter at strongside linebacker, until Chuck Howley passed him on the depth chart in the fourth game.
Edwards would end up forming with Howley and Jordan, one of the best linebacking corps in NFL history as part of the 'Doomsday Defense'.
[9] Referred to as "Fuzzy" by his teammates, Edwards' strength made him a difficult player to deal with against the run and he was also known to rarely make mistakes that could hurt the defense.
[11] In 1970, Edwards intercepted two passes against the Cleveland Browns, sealing a 6–2 win, that was key for the team to not only make the playoffs, but also advanced Dallas' first Super Bowl against the Baltimore Colts.
[13] Although overshadowed by Howley and Jordan, he was a key component in the Cowboys' defensive dominance during the late 1960s and early 1970s.
[10] On December 6, 2016, Edwards died in his sleep the day he was scheduled to undergo tests for a heart condition at a Waco hospital.
