Bobby excelled in several sports at a then-segregated Cleveland High School in Shelby, North Carolina. In the first two years, he played six-man football, playing under center the position halfback. During his junior year, his school converted to playing with an 11-man team where Bell served as quarterback. He won All-State honors.
College career
At the University of Minnesota, Bell was switched to the defensive line. He was a two-time All-American and the winner of the 1962 Outland Trophy, which is given to the nation's most outstanding interior lineman. He also finished third in Heisman Trophy voting. The Gophers with Bell were the 1960 National Champions, played in the 1961 Rose Bowl, and won the 1962 Rose Bowl. Bell was later inducted into the College Football Hall of Fame. He joined Alpha Phi Alpha fraternity, via the Mu Chapter, while at the University of Minnesota. At the age of 74, he completed his college degree at Minnesota by finishing the three remaining courses he required. He graduated on May 14, 2015, some 50 years after leaving college to play professional football.
Professional football career
He played for the Kansas City Chiefs, first in the American Football League from 1963 through 1969, and then in the NFL from 1970 through 1974. Bell was an AFL All-Star for six consecutive years, 1964 through 1969, and then an NFL Pro Bowler for three straight years. He was on two AFL Championship teams and a World Championship team. He was named to the All-Time All-AFL Team in 1970. He was inducted into the Chiefs Hall of Fame in 1980, and the Pro Football Hall of Fame in 1983. The Chiefs retired his uniform number 78. In 1999, he was ranked number 66 on The Sporting News' list of the 100 Greatest Football Players. One of Bell's finest moments came in the 1969 AFL divisional playoff game against the New York Jets. In a critical goal line stand, his key coverage on Jets running backMatt Snell stopped the drive and forced New York to kick a field goal. The 13-6 victory over the Jets propelled Kansas City to its first Super Bowl triumph. During a regular season game against Denver, the Broncos, trailing 24–17 late in the game, attempted an onside kick that was recovered by Bell, who promptly returned that kick for a 53-yard touchdown. Bell was noted for his one-of-a-kind athleticism at 6' 4" and 230 pounds and was reported to have run a 4.5 40-yard dash. Bell was possibly the most physically gifted linebacker in professional football history, for his speed at such a size made him ideal at outside linebacker. He was noted as one of the finest open-field tacklers in professional football history. He was also a great blitzer from the linebacker position. Chiefs records show Bell had 40 career quarterback sacks and he might have had more if he had played right linebacker, not the left linebacker. In that era, more often than not the right-side linebacker got the call to "dog" or blitz since more often than not the tight end would be lined up right, on the defense's left. Bell scored 9 touchdowns in his career: 6 off interceptions, 2 more touchdowns off fumble recoveries, and one off an onside kickoff return. Coach Hank Stram said that, "He could play all 22 positions on the field, and play them well." In addition to all that, he was regarded as one of the greatest long snapper centers for field goals and points-after-touchdowns in NCAA and AFL/NFL history.
