Colonels - If you're not going to add anything of value, please don't post.
MG - There's nothing in the guide that would suggest a + defense pressures the entry pass anymore than a - would. Here's the full discussion of +/-
Another area that needs to evaluated after every game is defensive positioning. This is where your knowledge of 3-point tendencies and points in the paint is very useful. You may position your players anywhere from +5 (take away perimeter) to -5 (take away inside) depending on where your opponent attempts to attack defenses. There are other effects of positioning, however.
For instance, playing a negative defense aids rebounding, but makes a team more likely to commit fouls. A positive defense has just the opposite effect, with less fouls but also less rebounding help. These factors, however, are generally considered secondary to the prime issue of where your opponent is shooting the ball.
