High school and college basketball players only get five fouls before getting fouled out of the game and NBA players get six. Although NBA players are more skilled, they get more leniency because nobody wants to see their favorite star fouled out of the game.

The game of basketball was invented by James Naismith in Springfield, MA. Naismith asked A.G. Spalding to create the game's first official basketballs and the NBA has used Spalding basketballs for decades. Today it's the official NBA game ball. Wilson makes the official game ball for the NCAA March Madness tournament.

The NBA resolves jump ball situations by having the involved players jump for a tossed ball. The NCAA uses a possession arrow. The possession arrow points to the team that lost the opening tip and then alternates after every jump ball situation.

2. Seven per half
   Five per quarter

An NBA team enters the "bonus situation" after being fouled five times per quarter. The foul count resets every quarter. If the quarter is coming to an end, a team enters the bonus after being fouled twice in the last two minutes.

College basketball teams like Syracuse are defined by zone defenses, but NBA teams rarely use the technique. Zone defense was once outlawed in the NBA. Today it's legal, but no defensive player can stand in the key for three seconds or more without guarding a specific player, so it makes it difficult. College basketball doesn't have a defensive three-second rule.
