Basket Ball

This is the video about the way LEBRON JAMES did the 720 dunk.
In the past, it has been possible for players to dunk a basketball and pull the rim down so hard that the glass backboard shatters, either around the rim itself or, at times, shattering the entire backboard. Reinforced backboards and rims have minimized this at the college and professional levels, but it still happens at lower levels. 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.[7] Darryl Dawkins of the Philadelphia 76ers was also notorious for two glass-shattering dunks in 1979 resulting in the league threatening to fine him and eventually installing breakaway rims.[8] At the beginning of his career, center Shaquille O'Neal also dunked so hard that he broke the supports holding two backboards during games against the New Jersey Nets and the Phoenix Suns, making them collapse to the ground; the glass would shatter all over anyone within a few feet (including the audience). 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. The NBA has made shattering the backboard a technical foul. This has assisted in deterring this action, as it can cost the team points.
