A player is disqualified in NCAA basketball when being charged with their 5th personal foul.
5 or 6 in the NBA
Each player gets 5 personal fouls.
Using NBA rules a player is only allowed 6 fouls before being disqualified. In an event where a player receives their 6th foul on the court with all substitutes being disqualified, the player on the court remains in the game and is charged a personal and team foul.
In the NBL you can get 6 fouls
It is a matter of opinion and personal tastes. I think Micheal Jordan is the best basketball player of all time.
You can substitute freely in basketball. As many players as there are on the bench, that's how many substitutes there are. Players may be taken out of a game and then put back into a game. There is no limit to the amount of times a player can be taken out and put into a game. The only limitation to substituting is that you may not put a player in that has exceed the number of personal fouls allowed in the league. Once a player exceeds that number, they are disqualified and not allowed to play for the rest of the game.
5 fouls is when a basketball player will be kicked out of a basketball game due to fouling out.
