Born in Kufai, Gombe State, Nigeria, his first name means "truth" in the Tangale language, and his last name means "inheritance". His family moved from Kufai to Wheaton, Illinois when Gado was half a year old; his father attended Wheaton College during that time. They returned to Nigeria when Samkon was two years old. After moving back to Nigeria, his father migrated again in 1990 to earn a doctorate degree in divinity at Columbia International University. A church in South Carolina made a financial contribution a year later so that Gado and his mother could also travel to America. He attended Ben Lippen School in Columbia, South Carolina, and lettered in football, basketball and baseball, earning all-state honors in football.
College career
Gado accepted a football scholarship from Liberty University, a then-Division I-AA school in Lynchburg, Virginia. He serverd mostly as a third-string running back, starting only two games during his tenure with the Flames. Injuries to two teammates, Eugene Goodman and Dre Barnes, saw Gado receive his largest amount of playing time as a senior after initially planning to redshirt. He wound up making the All-Big South team at the end of the season.
After going undrafted in the 2005 NFL Draft, Gado was signed by the Kansas City Chiefs in May after Liberty Ken Karcher recommended him to Chiefs offensive coordinator Al Saunders. He didn't play in the preseason because of a neck injury and was waived on August 29. He was signed to the practice squad on September 5 and was released again on October 4.
Green Bay Packers
On October 17, 2005, Gado was signed by the Green Bay Packers to the team's practice squad after running 4.43-second 40-yard dash in front of their scouts. On October 28, he was promoted to the active roster after Ahman Green ruptured his quadriceps tendon, Najeh Davenport broke his ankle and Tony Fisher fractured his first rib. He made his NFL debut the next day against the Cincinnati Bengals, recording one carry for eight yards. On November 6, 2005, ReShard Lee fumbled on his second carry against the Pittsburgh Steelers and was benched for the rest of the game. As Lee's sub, Gado registered over 20 carries during the game. On November 13, 2005, Gado started his first NFL game against the Atlanta Falcons. In the game, he rushed for over 100 yards and two touchdowns, and also caught a touchdown, leading to him being named NFC Offensive Rookie of the Week for Week 10. Gado's three touchdowns were the first by a Packer rookie since James Lofton in 1978. In the Week 14 game against the Detroit Lions, his third 100-yard effort of the season, Gado rushed for 171 yards against the Detroit Lions, a rookie record for the Packers, including a 64-yard touchdown run, while once again being given the Rookie of the Week award. A torn right medial collateral ligament, suffered late in the first quarter against the Baltimore Ravens on December 18, landed Gado on injured reserve. In 2006, Mike Sherman was fired and replaced with Mike McCarthy as the new head coach. During training camp, Gado suffered a minor groin injury but did not miss significant time. After an injury to William Henderson, Gado switched to a temporary fullback role. On September 12, 2006, after the first week of the NFL regular season, Gado was traded to the Houston Texans in exchange for running back Vernand Morency.
Houston Texans
In 2006, he reunited with former Packers coach Mike Sherman who was coaching the Texans offensive line. He was a backup behind Ron Dayne and Wali Lundy. Against the Jacksonville Jaguars in November 2006, Gado picked up a key fourth-quarter fourth down conversion to secure a 13-10 Texans win. In 2007, the Texans added free agent running back Ahman Green. Gado made the team over Lundy, playing in three games as a backup, while registering 18 carries for 46 yards and one touchdown. On October 23, 2007, the Texans released Gado after promoting running back Adimchinobi Echemandu from the practice squad.
Miami Dolphins
Shortly before Gado's release from Houston, the Miami Dolphins lost starting running back Ronnie Brown to a torn ACL, and the team subsequently claimed Gado off waivers in late October. He was cut by the team in favor of Ricky Williams on November 26, but after Williams suffered a season-ending injury that same day, Gado was re-signed to the active roster on November 28. He scored a pair of touchdowns during December. Gado, a restricted free agent in the 2008 offseason, was not tendered a contract by the team.
St. Louis Rams
Gado was signed by the St. Louis Rams on November 4, 2008 after wide receivers Drew Bennett and Dante Hall were placed on injured reserve. After playing in one game and being inactive for one game, he was released on November 19. Gado was re-signed by the Rams for the 2009 training camp, where he sustained a rib injury in a preseason game against the Kansas City Chiefs. He survived final roster cuts and spent the season as a reserve running back.
On August 17, 2010, Gado signed with the Tennessee Titans. He was released during final roster cuts on September 4, 2010.
Awards and honors
During his rookie season, Gado was named NFC Offensive Rookie of the Week in weeks 10 and 14 and was named NFL Offensive Rookie of the Month for November 2005. He also set the Green Bay Packers franchise record for single-game rushing yards by a rookie, tallying 171 yards on December 11, 2005.
