If you’ve spent any time watching basketball, you probably aware there is a basketball, a court, and some talented players, many of whom are wearing Nike shoes.   Professional basketball gets most of its players from the college circuit, and at first glace, pro and college ball looks pretty similar.   Upon closer observation, though, it’s easy to see that there are important differences between play at each level.  In addition to quarters (NBA) versus halves (NCAA), 3-point shooting distances, and different rules regarding fouling, there are other important differences to consider.   Getting a handle on these differences can help deepen your appreciation for the game.

There is a subtle difference in how possessions are handled in NBA versus NCAA ball.   Any dispute over which team gets possession of the ball is resolved with a jump ball.  In college ball, however, the only time a jump ball occurs is at the opening tip.  Possession simply goes back and forth between teams, with a “possession arrow” determining where possession will go next. 

Defense varies from college and professional ball as well.   As anyone familiar with the NBA rulebook can attest that the rules regarding defense are pretty intricate and complicated.   “Zone defense” is a strategy where a player guards a section of the floor, rather than an individual player.   This is not against the rules in NBA play, but the extent to which it can be used is restricted.   The NBA rule is called “Defensive Three Seconds,” which forbids the defending player to remain in the lane more than three seconds.  The rationale behind this rule is so that teams don’t just have their most imposing player camp out in one spot and bat at whatever is within his reach.   Zone play is definitely used in NBA play, but on a limited basis.   Man-to-man play is the name of the game in pro ball.

At the college level, however, this is not the case.   There are no rules governing zone defense, which results in a greater array of defense alignments.   Teams can build reputations for certain defense strategies, which eventually become team trademarks.  This makes for particularly exciting tournament play.

NBA and NCAA differences are important, albeit fairly subtle.  Knowing the differences between the rules of this sport makes for a much more satisfying viewing experience on the part of the fan.
