The restriction on using hands to impede the progress of an offensive player in the National Basketball Association underwent significant rule changes at the start of the 2004-2005 season. This alteration prohibited defenders from continually placing their hands on an opponent and using it to control their movement.
This rule modification aimed to increase offensive freedom and scoring. Prior to its implementation, perimeter players often found it difficult to drive to the basket due to the physical nature of defense. The change fostered a more free-flowing game, theoretically increasing scoring opportunities and making the game more appealing to spectators.
