Basketball isn't a static game; it evolves. Two significant rule changes in the NBA are the shot clock introduction and the three-point line addition.
The 24-second shot clock, introduced in 1954, quickened the pace of the game. Prior, teams could run out the clock once they had a lead. The shot clock made games more dynamic and viewer-friendly.
The three-point line, added in 1979, altered team strategies. It gave rise to sharpshooters and allowed teams to overcome large deficits quickly. Both changes have drastically shaped today's fast-paced, high-scoring NBA games.
