Three things that i see important. That all refer to the term PMT!
1) Paint
2) Movement
3) Technique
Paint being the main one. If you got no paint on the opposition then it will be very dificult to make those critical movements. Especially off the break!
Movement is key to reducing your angles on the opposition. The closer you get, the smaller the angle, the easier kills you get. There for the quicker you are rid of the opposition.
Paint and movement define your aggressiveness on the field. The more aggressive you are, the more those windows of opputunity open.
Lastly technique, determines how tight you are playing and how you play the game. Snapshooting is the main one. Snapshooting when trained properly is a killer skill. And will get you out of the **** in more times than not
Hope that helps.
Best person to ask really is Robbo or any of the nexus guys.
