The three rule changes approved by the NBA owners on Friday are not going to have a dramatic impact on this NBA season…
Until in a close playoff game in May it’s a little harder for a team getting offensive rebounds to just kill the clock. Or in that same playoff game, when clear path foul is called because an offensive player outraced a defender down the court.
As had been expected, the NBA’s Board of Governors — the owners — approved three rule changes for the coming NBA season. They are:
• The shot clock will reset to 14 seconds after an offensive rebound rather than 24 seconds. This has been experimented with in the G-League, the WNBA, and Summer League this year with some success. The goal is to speed up the pace of play, not letting a team get an offensive rebound then back it out and pound the ball for 20 seconds to kill time. Thing is, that was not much of a problem last season, as was noted at Nylon Calculus.

<em>Over 30 percent of offensive rebounds result in putbacks (the 0 Duration value on the graph) and 75 percent of offensive rebounds result in a possession that is five seconds or less. Only 6 percent of all offensive rebounds resulted in possessions that are 14 seconds or greater last year. Given that the league average for offensive rebounds was the lowest ever this past season at 9.7 per game, this rule would apply to roughly half a rebound per team per game last year.</em>
When fans will notice it, when it will have the intended impact is end-of-game situations — rather than a team grabbing offensive rebounds then killing the clock for 20 seconds, they will have to get up a shot, which will lead to the other team getting an opportunity.
• The league “simplified of the clear-path rule. The NBA’s old clear path rule was overly complicated and it led to things that looked like clear path fouls not being, and things that clearly were not being fouls. Here is the NBA’s explanation of the new rule, with some video help below.
A clear path foul is now defined as a personal foul against any offensive player during his team’s transition scoring opportunity in the following circumstances: the ball is ahead of the tip of the circle in the backcourt; no defender is ahead of the offensive player with the transition scoring opportunity; the player with the transition scoring opportunity is in control of the ball (or a pass has been thrown to him); and if the foul deprives his team of an opportunity to score.
As part of the clear path foul rule simplification, referees will no longer need to make judgment calls as to whether or not a defender was between (or had the opportunity to be between) the offensive player with the transition scoring opportunity and the basket. In addition, referees will no longer have to determine whether or not the defender was at any time ahead of the offensive player prior to committing the foul, nor will it be relevant whether or not a defender beat the offensive player with the transition scoring opportunity into the frontcourt. Further, plays of this nature will no longer have to originate in the backcourt (since transition scoring opportunities can originate in the frontcourt).
The NBA Board of Governors today unanimously approved rules changes in advance of the 2018-19 season. This includes a simplification of the clear path foul rule. To view examples of the clear path foul rule simplification, see the video below. pic.twitter.com/HQjJCqK5rv

• The NBA expanded what is defined as a “hostile act” so that replay can be triggered more easily. Currently, to be a hostile act according to the NBA rulebook it has to be an altercation between players that is “not part of a normal basketball play” or where a player “intentionally or recklessly harms or attempts to harm another player.” Broadening the scope of this will give referees more chances to review off-ball or other altercations, and these are the kinds of serious situations the league should review.
