In his senior season, the Crimson Tide fell short of another national championship with a 10–1 record. In his final game for the Tide, Jordan recorded 31 tackles in a 17–0 victory over Oklahoma in the Orange Bowl. For his performance, he received his second MVP award in a bowl game. At the end of his senior year, he received unanimous All-American status and the Lineman of the Year award.
During his career for Alabama, Jordan received high praise from Bryant, who stated, "He was one of the finest football players the world has ever seen. If runners stayed between the sidelines, he tackled them. He never had a bad day, he was 100 percent every day in practice and in the games."
Jordan was usually the smallest middle linebacker in the league at only 6'-1" and 215 pounds, but his competitiveness and drive made up for his lack of size. Head coach Tom Landry said of Jordan, "He was a great competitor. He was not big for a middle linebacker, but because of his competitiveness, he was able to play the game and play it well. His leadership was there and he demanded a lot out of the people around him as he did of himself." He ran Landry's "Flex" defense on the field with unmatched intensity and efficiency. He watched game film endlessly; his contract included a projector for his home.
He became the franchise's all-time leader in solo tackles (743) in his 14 seasons with the Cowboys. He was a two-time All-Pro and a five-time Pro Bowler. He also helped the Cowboys to three Super Bowls and five NFC Championship games. Jordan was an able defender against the run and pass, and had a penchant for recovering loose footballs. He remains tied for second in club history with 16 career fumble recoveries.
More than 25 years after his retirement, Jordan still ranks second in Cowboys' history in career solo tackles with 743, second in career assisted tackles with 493 and second in combined total tackles with 1,236. He also holds the third and fourth highest totals of solo tackles in a single season with 100 in 1975 and 97 in 1968. In his 14 NFL seasons, he intercepted 32 passes (seventh in club history), returning them for 472 yards and three touchdowns.
He had three sons, David, Patrick, and Chris Jordan. David married and had three daughters, Bradford, Meredith, and Dabney. Patrick (who goes by the name Lee) married and had three daughters, Julia, MaryBeth, and Kathryn. Chris married and had two sons, Thomas and Bryant. He now resides in Dallas, Texas, as well as his house on Mobile Bay in Point Clear, Alabama.
