Problem: Robert Lee "Bullet Bob" Hayes (December 20, 1942 - September 18, 2002) was an Olympic sprinter turned American football wide receiver in the National Football League for the Dallas Cowboys. An American track and field athlete, he was a two-sport stand-out in college in both track and football at Florida A&M University. He has one of the top 100 meter times by NFL players. Hayes was enshrined in the Dallas Cowboys Ring of Honor in 2001 and was selected for induction in the Pro Football Hall of Fame in January 2009.

At the 1964 Summer Olympics, in Tokyo, Hayes had his finest hour as a sprinter. First, he won the 100m and in doing so tied the then world record in the 100 m with a time of 10.06 seconds, even though he was running in lane 1 which had, the day before, been used for the 20 km racewalk and this badly chewed up the cinder track. He also was running in borrowed spikes because one of his shoes had been kicked under the bed when he was playing with some friends and he didn't realize until he got there. This was followed by a second gold medal in the 4x100 meter relay, which also produced a new World Record (39.06 seconds).  His come-from-behind win for the US team in the relay was one of the most memorable Olympic moments. Hand-timed between 8.5 and 8.9 seconds, his relay leg is the fastest in history. Jocelyn Delecour, France's anchor leg runner, famously said to Paul Drayton before the relay final that, "You can't win, all you have is Bob Hayes." Drayton was able to reply afterwards, "That's all we need." The race was also Hayes' last as a track and field athlete, as he permanently switched to football after it, aged only 21.  In some of the first meets to be timed with experimental fully automatic timing, Hayes was the first man to break ten seconds for the 100 meters, albeit with a 5.3 m/s wind assistance in the semi-finals of the 1964 Olympics. His time was recorded at 9.91 seconds. Jim Hines officially broke 10 seconds at the high altitude of Mexico City, Mexico in 1968 (and on a synthetic track) with a wind legal 9.95 which stood as the world record for almost 15 years. The next to surpass Hayes at a low altitude Olympics was Carl Lewis in 1984 when he won in 9.99, some 20 years later (though Hasely Crawford equaled the time in 1976).  Until the Tokyo Olympics, world records were measured by officials with stopwatches, measured to the nearest tenth of a second. Although fully automatic timing was used in Tokyo, the times were given the appearance of manual timing. This was done by subtracting 0.05 seconds from the automatic time and rounding to the nearest tenth of a second, making Hayes' time of 10.06 seconds convert to 10.0 seconds, despite the fact that the officials with stopwatches had measured Hayes' time to be 9.9 seconds, and the average difference between manual and automatic times was typically 0.15 to 0.20 seconds. This unique method of determining the official time therefore denied Hayes the record of being the first to officially record 9.9 seconds for the 100 meters. The first official times of 9.9 seconds were recorded at the "Night of Speed" in 1968.

Problem: Jens Ingemar Johansson (Swedish: ['ING:emar 2ju:hans,son]; 22 September 1932 - 30 January 2009) was a Swedish professional boxer who competed from 1952 to 1963. He held the world heavyweight title from 1959 to 1960, and was the fifth heavyweight champion born outside the United States. Johansson won the title by defeating Floyd Patterson via third-round stoppage, after flooring him seven times in that round. For this achievement, Johansson was awarded the Hickok Belt as top professional athlete of the year--the only non-American to do so in the belt's entire 27-year existence--and was named the Associated Press Male Athlete of the Year and Sports Illustrated Sportsman of the Year.

Johansson's introduction to the top rank of the sport was inauspicious. At age nineteen he was disqualified for passivity at the Helsinki 1952 Summer Olympics in the heavyweight competition in a fight against eventual Olympic gold medalist Ed Sanders. Johansson maintained he was not evading Sanders (who also got a warning for passivity), but rather was trying to tire his opponent. Johansson said he had been limited to a 10-day training camp, had only trained with newcomers, and had been told by his coach to let Sanders be the aggressor. Nevertheless, his silver medal was withheld for poor performance and only presented to him in 1982.  Johansson had earned his spot in the Olympics by winning the Swedish National Championship earlier the same year, 1952, after he knocked out his opponent in the first round of the final.  After the Olympics Johansson went into seclusion for six months and considered quitting boxing. However, he returned to the ring and turned professional under the guidance of the Swedish publisher and boxing promoter Edwin Ahlquist, subsequently winning his first 21 professional fights. He won the Scandinavian pro title by knocking down and outscoring the Dane Erik Jensen (breaking his right hand in the process). A broken hand and a one-year military service kept him out of the ring until late 1954. In August 1955, in his twelfth professional fight, Johansson knocked out former European Heavyweight Champion Hein ten Hoff in the first round. He took the Scandinavian heavyweight title in 1953 and, on 30 September 1956, he won the European Heavyweight Championship by scoring a 13th-round KO over Italy's Franco Cavicchi in Milan for the European title.  Johansson successfully defended his European Crown against ranked heavyweights Henry Cooper (fifth-round KO on 19 May 1957) and Joe Erskine, with a TKO in 13 on 21 February 1958.
