Exploiting Mismatches
Study, learn, practice, and perfect one-on-one, pick-and-roll, and give-and-go offenses.  Every offense designed by every coach is an offshoot of these three basic offense moves and these are the offenses all players are attempting to play on playgrounds, driveways, backyards, dirt, sand, and asphalt courts around the world. 
Here's what normally happens during an organized league game.  The coach calls for a play that has been practiced hundreds of times and even run during other games.  As your team sets up for this designed play you notice your opponents are not cooperating (the opposing team has the audacity of not allowing you to run your designed play) at this moment your only option is an audible.  Scoring opportunities are developed around mismatches.  Mismatches present themselves in many different ways during the course of a game.  Some obvious examples are: a fast break opportunity when a defense gathers up a rebound, becoming the offense, and a player is down court under the basket all alone.  An accurate full court pass to that open player turns into an uncontested lay up; Because of a broken play a 5'2" point guard is down in the paint guarding a 6'9" power forward.  A pass into the post results in what is essentially an uncontested lay up; Because of a switch in man to man coverage a 6'11" center is out on the perimeter guarding a 6' point guard.  With a beautiful cross over dribble and a blow-by move the point guard drives in for an uncontested lay up.  These are but three examples of mismatches created during the flow of a game.
An offense's responsibility is creating, recognizing, and taking advantage of mismatches.   This is what ALL offensive plays are designed to do.  If a designed play fails, then a team looks to create a mismatch and exploit that mismatch with a one on one move, a pick and roll move, or a give and go move whichever one will exploit the most obvious mismatch presently on the court.  An open player under the basket is without a doubt the best mismatch on the court.  Three plays that create an open man under the basket are the pick and roll, the give and go and a back door play (which is generally created as option #2 from a one on one, a pick and roll or a give and go).  If players really understand the theories and branch theories behind these simple basketball offenses that same understanding will afford them the knowledge to properly defend any offense with a simple, elegant and effective defense. 

Defense is the best offensive teacher.  Players, ask your coaches to teach you the rules of basketball and defensive drills.  Search online for defensive drills or find books in the library written by successful coaches about the defensive drills they teach and the theory behind why and how they teach these specific defense drills. 
What's the difference between plays and drills?  Plays condition your mind.  Drills condition your body and your mind.  You can practice these defensive drills on your own so you'll be able to perform the awkward moves a defensive player must be able to execute, i.e. running backwards and quickly shuffling sideways.  You players waiting for coaches to teach you the rules of basketball, basic basketball offense, and waiting for coaches to condition you are destined to 'ride the pine.'  All players are not, but all players can be, superstars.  But you must take responsibility for yourself.  |
"With ordinary talent and extraordinary perseverance, all things are attainable." --T.F. Buxton.
"Nothing in the world can take the place of persistence and determination. Talent will not; nothing is more common than unsuccessful men with talent.  Genius will not; unrewarded genius is almost a proverb.  Education will not; the world is full of educated derelicts. 
"Persistence and determination alone are omnipotent." --Calvin Coolidge, 30th President of the United States, 1932.
Observe Larry Bird, a player of the highest degree.  His only natural talents are a basketball mind, persistence, and determination. 

When NCAA coaching staffs spend as much time training and educating high school programs (coaches) and AAU programs (coaches), and youth basketball as they do retraining high school graduates, within four years they can be reaping the fruits of their labor.  AAU and high school basketball programs trained by the NCAA will be capable of properly training the local grade school programs.  A system like this allows elite NCAA coaching staffs to indirectly coach young players to develop proper skills in a logical, progressive, and supervised program.

When players and teams are deluged with, and extremely well coached in, executing one-on-one, pick-and-roll and give-and-go offensive plays until reaching college basketball age, the already stellar play in NCAA will become absolutely mind boggling.  This training process is akin to students mastering addition and subtraction before attempting multiplication and division or tackling advanced mathematics and physics.  Too much time is being spent explaining the rules of basketball and nurturing NCAA players' basic skills and education.  These basics should be second nature by the time players reach NCAA programs.  NCAA coaching staffs should be teaching and coaching advanced theory instead of wasting precious time retraining players' non-existent, poor and/or under developed basic skills and education. 
Who's to blame when these gifted yet underdeveloped players reach the ranks of the NCAA?  The NCAA basketball program itself. 

Basketball teams are allowed only so much organized practice time, as laid out in the rules for grade school, high school, and college teams.  As a player, if you're not in 'game shape' on the first day of practice you're causing your team a disservice.  The last thing a coach wants is to lose a basketball game because of a lack of conditioning.  Your coach is obligated to spend valuable practice time on conditioning drills if you report to practice physically out of shape.  You leave your coach no choice because physical conditioning is the major deterrent to sports injuries.

I'm telling you basketball is a simple game.  An offense designed around one-on-one, pick-and-roll and give-and-go, and an elegant defense designed to defend a one-on-one, pick-and-roll and give-and-go.
