NBA: A clear path foul results in 2 free throws.
2K9: A clear path foul results in 1 free throw.
NBA: If the ball makes contact firstly with a defensive players foot or leg, a 'kick ball' violation will be issued, resulting in the ball to be taken out by the sideline for the team that had possession of the ball. The shot clock also gets reset to 14, if I recall correctly.
2K9: No violation. If a bounce pass gets kicked around, play continues. This violation added in 2k10 would at least settle down people who get frustrated with unnecessary and uncontrollable bounce passes that lead to turnovers in 2k9.
NBA: When throwing the ball inbounds, the defensive player guarding the inbound pass must be at a certain distance from the inbounder. If they fail to comply, they get issued with a delay of game warning. Every other delay of game violation that commences will result in a technical foul and the team with the ball will be rewarded with a free throw.
2K9: In 2k9, you can keep inching your way right up to the face of the inbounder without penalty before the inbounder has even been handed the ball by the referee. The inbounder often turns the ball over if the defender has long enough arms and will often deflect the pass resulting in a turnover.
NBA: In a jumpball, the two jumpers may only tap the ball. They are not allowed to gain possession of the ball before one of the eight non-jumpers touches the ball.
2K9: In 2k9, there is a cheap way of stealing the ball after the tap to give your team the starting possessions in the 1st, 2nd and 3rd quarters. I won't tell people how it's done but simply applying this rule would stop this cheap (currently unknown to most) method used in 2k9.
NBA: The only time you can pass into the backcourt when inbounding from midcourt or frontcourt is when you're in the last 2 minutes of the 4th quarter and/or overtime.
2K9: As long as a player doesn't physically carry the ball over the half court line, a player can throw it into the backcourt at any point during a game without penalty.
NBA: For goaltending or offensive interference violations to occur, the ball, in the judgment of the official, must have a chance to score. Of course, this also applied to shots that are still hanging on the rim.
2K9: The whistle blows way too much, even on shots that obviously have no chance of going in and have already come off of the rim.
NBA: Goaltending applies to shooting fouls.
2K9: Apparently in 2k9, it does not. You can goaltend a shot after a foul call without awarding two points to the shooter.
In fact, you can even goaltend a shot without penalty if the clock has stopped, period. Which means you can goaltend a shot where the player was fouled and they won't recieve any points for it. You can goaltend a buzzer beater without handing over the points as long as the time in the quarter has ended and the ball is still deciding on whether it wants to go in the hoop or not.
NBA: You may not block a shot from underneath/through the hoop, this is goaltending.
2K9: I have seen this action occur from time to time in 2k9 without any penalization, though it isn't an everyday occurrence (thank god). Still though, fix this for 2k10.
NBA: If a shot is made during a 'loose ball foul' or 'over the back' foul by the defense, the shot should count.
2K9: Commiting a 'loose ball foul' or 'over the back' foul by the defense will nullify any made shot. WTF? How many times in team-up mode do I have to see people intentionally pushing players in the backcourt (loose ball foul) to stop a fast break dunk/layup?
I'm personally not sure on this rule, but in the 2k trivia questions it states what I've typed below in the 'NBA rule'.
NBA: During a 20 sec timeout you can only substitute one player.
2K9: During a 20 sec timeout you can change your entire lineup.
