How to play defence in sports ?

The role of a defender is different from an offender, a defender defences and an offender attacks.

To play offence, a player needs skill and sometimes a variety of skills. To play defence is much more easy, you do not need skill but tactics, your duty is to prevent an offender from scoring and nothing else. On the other hand, an offender not only tasked with the duty of scoring, he also needs to do it in style.

The single biggest mistake a defender can make is mental lapse, even a split second of mental lapse can cost a game and you will be forever condemned to hell.

The biggest asset of a defender is to know his limit, he must rationalize his energy to cover a limited defence-able area for the entire game and the goal is to tired out the offender eventually.
