On This Day in History: April 23, 1993
32 Years Ago Today: Shaquille O'Neal unleashed one of the most unforgettable displays of raw power in NBA history, dunking with such tremendous force that he completely shattered the backboard support system. The entire hoop came crashing down, bringing the game to a halt.
This monumental moment wasn't just a testament to Shaq's superhuman strength—it marked the end of an era. O'Neal's destruction would be the last time a backboard was ever broken in an NBA game, thanks to subsequent technological advancements and rule changes.
The Backboard Evolution: From Peach Baskets to Shatterproof Glass
The basketball backboard has come a long way since Dr. James Naismith created the sport in 1891 with just a peach basket mounted on a 10-foot indoor running track. Let's trace this remarkable evolution:
1891: The original basketball "hoop" featured no backboard at all—just a peach basket. Missing meant chasing the ball up to the track.
Early 1890s: Wire mesh fences were installed to prevent balls from escaping to the track level.
1895: The first innovation in basket design—a trap door net appeared, allowing referees to pull a string to release the ball instead of climbing ladders.
1904: Wooden backboards became mandatory, replacing mesh wire and creating the possibility for bank shots.
1909: Glass backboards emerged, offering fans clearer views of the action (though dunking wasn't yet part of the game).
1916: Two critical developments:
Glass backboards were temporarily banned due to safety concerns
Backboards were moved two feet away from walls, preventing players from using walls for leverage—the first step toward modern court geometry
1940s: Tempered glass backboards became common, providing a more consistent surface for bank shots. A rectangular "target box" was added above the rim as an aiming point.
The Era of Shattered Dreams (and Glass)
As basketball evolved and players became more athletic, backboards faced unprecedented challenges:
1946: Boston Celtic Chuck Connors (later famous as TV's "The Rifleman") shattered a glass backboard during pre-game warmups with just a set shot.
1960s: Gus "Honeycomb" Johnson of the Baltimore Bullets became the "first serial breaker," shattering three backboards with explosive dunks. His physical play (at 6'6", 230 pounds) foreshadowed concerns that would later lead the NCAA to temporarily ban dunking.
1970s: The ABA era brought spectacular dunkers and spectacular destruction:
Charlie "Helicopter" Hentz made history by shattering both backboards in a single game between the Pittsburgh Condors and Carolina Cougars
Darryl "Chocolate Thunder" Dawkins shattered two backboards in three weeks in 1979, with fans collecting "Darryl's Diamonds" as souvenirs
Engineering Solutions
The constant destruction of equipment called for innovation:
1976: Arthur Ehrat invented the breakaway rim using a coil spring originally developed for John Deere tractors. The rim could flex and absorb the force that would otherwise shatter the backboard.
1982: Breakaway rims were patented and became standard at all levels of basketball. Darryl Dawkins himself tested and approved the design when he couldn't break it.
1990s: The Shaq Attack required further improvements:
Direct mount systems with steel support arms passing through the glass were developed
Rules against hanging on the rim were strictly enforced as technical fouls
Enhanced support structures were created to withstand the force of 300+ pound athletes
The Legacy
Thanks to these technological advances, the last NBA backboard broken during a game was by Shaquille O'Neal on April 23, 1993. Today's backboards use technology similar to smartphone screens—the same glass that protects your pocket device protects players from dangerous shards during thunderous dunks.
This evolution represents not just engineering innovation but basketball's growth from a simple pastime to a high-flying spectacle requiring specialized equipment to handle ever-more-athletic players.
