In general, elite athletes tend to be taller and larger than the average human. Part of their advantage in competition is their physical size.
But not all athletes are made equally. Some are so tall, so big, so large that they're now more famous for their physical presence than what they accomplished on the court or field.
After the Phoenix Suns drafted Oliver Miller in 1992, he quickly earned the nickname "The Big O" because of his enormous size. He was 6 foot 9 and weighed over 300 pounds (136.08 kg) for much of his career. At the time, he was the heaviest person to ever play in the NBA.
Miller played in the NBA for eight seasons. He also spent time playing in Europe as well as for the Harlem Globetrotters.
Ice skating isn't easy. Now trying ice skating while weighing 270 pounds (122.47 kg). And you're sharing a rink with some very tough guys who would love nothing more than to check you hard. But that's what John Scott did night after night for almost ten seasons in the NHL.
In 2016 Scott was infamously voted into the All-Star game by the fans. Some thought that his stats that year did not merit an invitation, but he still won the popular vote and ended having a good performance in the game.
You know you're tall when you are given the nickname "The Big Unit." That's what fans called 6 foot 10 left-handed pitcher Randy Johnson, and he earned every inch of that title.
He won a World Series ring and numerous Cy Young awards, but many on the internet remember Johnson and his devastating fastball for another moment. He once inadvertently vaporized an unlucky bird that flew between the pitcher's mound and the batter's box just as Johnson released his pitch.
Although his real name is Danny Jones, this 6 foot 7 personal trainer got his name from somebody on Twitter who claimed he looked more like a tree than a man.
Jones is based in Southern California and has used his newfound fame to help grow his own social media (big)footprint. His pictures and inspiring messages are reaching people around the world.
Eddy Curry was an imposing force of nature on the court. Standing at an even 7 feet (2.13 meters) and weighing close to 300 pounds (136.08 kg), Curry was an imposing force of nature on the court even by NBA standards.
Although he was considered one of the best high school basketball players and was drafted into the NBA straight from high school, Curry didn't start playing the game until junior high.
During his career in the NBA, he played on four different teams, including the Miami Heat's 2012 champion squad. Curry ended his career playing basketball in China.
Although he stands less than 6 feet tall, golfer John Daly's rotund figure made him one of the most recognizable players on the course. Before quitting alcohol and having lap-band surgery, Daly reportedly weighed 185 pounds (83.91 kg). This made him popular with the regular joes of the world and made him stand apart from the typical professional golfer's build.
With a tall and slender frame, Blanka Vlasic was almost destined to be one of the best (and tallest) Olympic high jumpers of all time. The Croatian athlete stood 6 foot 4 yet only weighed 165 pounds (74.84 kg). She was a double Olympic medalist as well as a two-time world champion.
It must be in Vlasic's genes to be such a dominant athlete. Her mother was an accomplished amateur athlete, and her father was a decathlon record holder.
This offensive lineman is considered to be one of the heaviest athletes to play in the NFL for a sustained amount of time. He reportedly weighed more than 400 pounds (181.44 kg) for much of six seasons.
After his career in the NFL, he spent some time playing for the AFL. By 2012 there were reports Gibson was playing in a developmental league and was tipping the scales at 500 pounds (226.8 kg).
Jan Koller is instantly identifiable to most soccer fans. Standing at 6 foot 8 inches, he was hard to miss on the field. The Czech player started out as a goalkeeper but later found his calling as a striker.
Because of his unique size, Koller earned a number of unique nicknames, including "Dino" and "Human Lighthouse."
Standing at an even 7 feet (2.13 meters), Stefan Struve is the tallest fighter in UFC history. Struve grew up in the Netherlands and didn't start participating in martial arts until he was a teenager. He made his professional debut at the age of 17.
Having such a tall stature, Struve has rightfully earned the nickname of the "Skyscraper."
Although he never played in the NBA, Suleiman Ali Nashnush holds the record for being the tallest professional basketball player of all time. Standing at 8 foot 1, he played center for the Libyan national team.
Even though his height gained him international fame and led to a brief movie appearance, Nashnush once underwent surgery to correct his abnormal growth.
Everyone knows that retired Olympic sprinter is really fast, but did you also know Usain Bolt is really tall? The eight-time gold medalist stands at a towering 6 feet 5 inches. That makes him the tallest Olympic sprinter in history.
The average sprinter tends to be several inches smaller than that. Generally speaking, the taller you are, the less speedy you are on the track because of the size of your frame. But that didn't stop Bolt from developing the perfect sprinting gait.
Although not nearly as tall or heavy as some other athletes on this list, Maria Sharapova is one of the tallest professional female tennis players of all time. She stands at 6 foot 2 and weighs 165 pounds (74.84 kg). She also has very large feet and reportedly wears size 11 shoes.
Sharapova is almost just as famous for the loud grunting noises she makes while playing tennis. She's had opponents complain to the umpires about the sounds, and her grunts once were recorded reaching a decibel of 101 during a match in 2005.
Shawn Bradley was destined to be a giant athlete. The former NBA star's mom was 6 feet tall, and his father stood at 6 foot 8. By the time Bradley was done growing, he towered over both of them at a height of 7 foot 6. His playing weight was listed at 275 pounds (113.4 kg).
Bradley used his height to be a standout athlete in high school, where he played football and baseball as well as basketball. He is considered to be one of the best high school basketball players ever in the history of Utah.
Most modern NFL kickers make sure they stay in shape. Since they tend to be some of the smallest men on the roster, they want to remind their teammates that they're just as much of an athlete as the rest of them.
But it wasn't always that way. Take kicker Tom Dempsey. He spent a decade in the NFL in the 1970s despite weighing around 250 pounds. The excess weight didn't seem to hinder his skills. For more than 40 years, he held the record for kicking a 63-yard field goal.
