Slam dunk
A slam dunk, also simply known as a dunk, is a type of basketball shot that is performed when a player jumps in the air, controls the ball above the horizontal plane of the rim, and shoves the ball directly through the basket with either one or both hands. It is a type of field goal that is worth two points. Such a shot was known as a "dunk shot" until the term "slam dunk" was coined by former Los Angeles Lakers announcer Chick Hearn.
The slam dunk is usually the highest percentage shot and a crowd-pleaser. Thus, the maneuver is often taken from the basketball game and showcased in slam dunk contests such as the NBA Slam Dunk Contest held during the annual NBA All-Star Weekend. The first incarnation of the NBA Slam Dunk Contest was held during the half-time of the 1976 ABA All-Star Game.
A study was carried out in 2015 to show the effectiveness of different shot types, including slam dunks. The study was carried out across five different levels of basketball. Overall the study showed that slam dunks were a very effective way of scoring in the game of basketball, particularly in the NBA, which had the highest dunk percentage in the study.
History
, playing for the McPherson Globe Refiners, dunked the ball in 1936 in Madison Square Garden. The feat was immortalized by Arthur Daley, Pulitzer Prize winning sports writer for The New York Times in an article in March 1936. He wrote that Joe Fortenberry and his teammate, Willard Schmidt, instead of shooting up for a layup, leaped up and "pitch the ball downward into the hoop, much like a cafeteria customer dunking a roll in coffee".During the 1940s, 7-foot center and Olympic gold medalist Bob Kurland was dunking regularly during games. Yet defenders viewed the execution of a slam dunk as a personal affront that deserved retribution; thus defenders often intimidated offensive players and thwarted the move. Kurland's rival big man George Mikan noted "We used to dunk in pregame practice, not in the game." Satch Sanders, a career Boston Celtic from 1960 to 1973, said: "in the old days, would run under you when you were in the air... trying to take people out of games so they couldn't play. It was an unwritten rule."
Still, by the 1950s and early 1960s some of the NBA's tallest and strongest centers such as Bill Russell and Wilt Chamberlain had incorporated the move into their offensive arsenal. Slightly smaller players at forward and guard then began to dunk, helping to popularize the move, like "Jumping" Johnny Green, Gus Johnson, Elgin Baylor, and Connie Hawkins in the 1960s and David Thompson and Julius Erving in the 1970s. This transformed dunking into the standard fare it is today.
1956 rule changes
In the 1950s, Jim Pollard and Wilt Chamberlain had both dunked from the free throw line—15 feet from the basket. Chamberlain was able to dunk from the free-throw line without a running start, beginning his forward movement from within the top half of the free-throw circle. This was the catalyst for the 1956 NCAA rule change which requires that a shooter maintain both feet behind the line during a free-throw attempt. An inbounds pass over the backboard was also banned because of Chamberlain. Offensive goaltending, also called basket interference, was introduced as a rule in 1956 after Bill Russell had exploited it at San Francisco and Chamberlain was soon to enter college play. While at the University of Kansas, Chamberlain was known to have dunked on an experimental 12-foot basket set up by Phog Allen. When Chamberlain dunked the ball it was called a "dipper dunk."Lew Alcindor rule
Dunking was banned in the NCAA and high school sports from 1967 to 1976. Many people have attributed the ban to the dominance of the college phenomenon Lew Alcindor ; the no-dunking rule is sometimes referred to as the "Lew Alcindor rule." Others have attributed the ban to racial motivations, as at the time most of the prominent dunkers in college basketball were African-American, and the ban took place less than a year after the 1966 NCAA University Division basketball championship game, wherein a Texas Western team with an all-black starting lineup beat an all-white Kentucky team to win the national championship. Under head coach Guy Lewis, Houston made considerable use of the on their way to the Final FourBreakaway rims
In the NBA, in 1976 Arthur Erhat filed a patent for "a rim that had give but immediately returned to its original position," making dunking safe for the first time by significantly reducing the shattering of backboards. In 1979, Erving's teammate and center Darryl Dawkins twice shattered NBA backboards with dunks leading to a quickly-enacted rule making it an offence to break the backboard. Technology has evolved to adapt to the increased strength and weight of players to withstand the force of such dunks, such as the breakaway rim changes to the material used for the backboards, and strengthening of the goal standards themselves. The invention by Arthur Ehrat to create the breakaway rim with a spring on it led to the return of the dunk in college basketball.All-star power forward Gus Johnson of the Baltimore Bullets was the first of the famous backboard breakers in the NBA, shattering three during his career in the 1960s and early 1970s. Luke Jackson also shattered a backboard in 1968. In the ABA, Charlie Hentz broke two backboards in the same game on 6 November 1970 resulting in the game being called.
The NBA has made shattering the backboard a technical foul, although it will not count towards a player's count of seven that can draw a suspension, or two towards ejection from a game, though it counts towards a player's count of six personal fouls. This has assisted in deterring this action, as it can cost the team points.
Slam Dunk Contest era
The first-ever Slam Dunk Contest was held on January 27, 1976 at McNichols Sports Arena in Denver during halftime of the 1976 ABA All-Star Game, the league's final All-Star game before the completion of the ABA–NBA merger. Erving defeated Thompson in the championship round, after leaping from the free-throw line. The other participants were Artis Gilmore, George Gervin, and Larry Kenon.The NBA held its first Slam Dunk Contest as a one-off, season-long event similar to NBA Horse event held the following season. During halftime at each game, there was a one-on-one slam dunk competition. Former ABA player Darnell "Dr. Dunk" Hillman was named the winner that season. Although he received the winner's $15,000 check, Hillman did not receive a trophy until 2017.
Modern era
The Houston Cougars from 1982 to 1984, with Hakeem Olajuwon and Clyde Drexler, were known as Phi Slama Jama. The national champion 1982 North Carolina Tar Heels also featured two notable dunkers: James Worthy and Michael Jordan.Larry Nance won the first modern dunk contest in 1984. Spud Webb at defeated Dominique Wilkins in the 1986 dunk contest.
Michael Jordan nicknamed "Air Jordan" for his dunking ability, popularized a dunk referred to by some fans as the "Leaner" in 1987 contest. This dunk was so called because Jordan's body was not perpendicular to the ground while performing the dunk. TNT viewers rated it "the best dunk of all time" over Vince Carter's between-the-legs slam. In the 1988 NBA Slam Dunk Contest, which came down to Michael Jordan and Dominique Wilkins, Jordan dunked from the free-throw line, much like Erving, but parted his legs making his dunk arguably more memorable than Erving's.
Twice in his rookie season during games, center Shaquille O'Neal dunked so hard that he broke the hydraulic support of one goal standard and broke the welds holding up another goal standard, causing the basket to break off and fall to the floor, although in neither case did the glass break. This resulted in reinforced backboard supports as well. During that same season, New Jersey's Chris Morris shattered a backboard in a game against the Chicago Bulls.
In the 1996 NBA Slam Dunk Contest, winner Brent Barry dunked from the free-throw line. Barry received 49 for the dunk. Kobe Bryant won the 1997 Dunk Contest.
2000–present
dunked while leaping over 7-foot-2 French center Frédéric Weis in the 2000 Summer Olympics. The French media dubbed it "le dunk de la mort"—"the dunk of death". In the 2000 dunk contest Carter used an elbow hang along with his reverse 360 windmill dunk and between-the-legs dunk. When performed, much of the audience was speechless, including the judges, because none had seen these types of dunks before.In the 2008 Sprite Rising Star's Slam Dunk Contest Dwight Howard performed the "Superman" dunk. He donned a Superman outfit as Orlando Magic guard Jameer Nelson tied a cape around his shoulders. Nelson alley-ooped the basketball as Howard jumped from within the key side of the free throw circle line, caught the ball, and threw it through the rim. This dunk is somewhat controversial, as his hand was not over as well as on a vertical plane to the rim. Some insist that it should in fact be considered a dunk because the ball was thrust downward into the basket, meeting the basic definition of the dunk.
During the 2009 NBA dunk contest, Howard had a separate goal brought onto the court, and the rim was noticeably significantly higher than a standard goal. Howard, after going into a 1950s-era telephone booth and again fashioning the Superman attire, caught a pass from Nelson and easily completed a two-handed dunk on the higher goal. While this was not performed for record-setting purposes, the dunk received a perfect score and a warm response from the crowd, in part because of its theatrics. Also in this contest, 5'9" guard Nate Robinson wore a green New York Knicks jersey and green sneakers to represent Kryptonite, playing on Howard's Superman theme. He used a green "Kryptonite" ball, and jumped over the 6'11" Howard prior to dunking. This dunk and the theatrics could have won the competition for Robinson, who was voted the winner by the NBA fans. Robinson then thanked Howard for graciously allowing him to dunk over him, asking the crowd to also give Howard a round of applause.
More recently, the Clippers earned the nickname "Lob City" from 2011 onwards, with Chris Paul utilizing alley-oop passes regularly to teammates Blake Griffin, and DeAndre Jordan.
JaVale McGee currently holds the world record for Most Basketball Dunks in a Single Jump: three. While competing in the 2011 NBA Sprite Slam Dunk Contest, McGee jumped with two balls in his possession and dunked each prior to receiving and slamming an alley-oop pass from then teammate John Wall.
In the 2016 NBA Slam Dunk Contest, Zach LaVine dunked from the free throw line on three occasions: One Hand, Windmill, and Between the Legs. All of the Dunks received a score of 50 for the dunk and won the Dunk contest.
