The Brooklyn Nets are the second worst defensive team in the league. They allow an average of 113.2 points per game to opposing teams. It is a major reason why they are 8-14.
Kenny Atkinson, similar to most NBA coaches, instructs his guards to fight over the top of screens. This prevents opposing ball handlers from stepping back for an open jumper if a defender goes under the screen.
The Nets coaching staff instructs their big men to hang back on screens and stay in the paint. Atkinson feels they are not athletic enough to challenge ball handlers coming off screens.
