Why defence (defenders) is more imporant than attack (attackers) in a game

After watching yet another fine game of football, my buddy Francis and I got into a conversation around what was more important - defenders or attackers? Since, this is sports-related, this debate is a little more relevant to guys. The debate topic (also asked on Twitter) was/is "What is more important to the success of a team in a sporting or physical activity? A good defence or a good attack?" Francis and I agreed that 'defence' is more important and critical. Here are some points that illustrate our point; series of tweets coming up :-)

Attackers might score the goals but defenders & defense wins championships #discos

You might see the attackers and be pleased with the work but when the defense is working, u wont be seeing the attackers then. #discos

You can lose the game even if your attack is working well n you have a terrible defend. Easier to attack than defend. #discos

If you have a great defence, no matter how bad your attack is, you can stay in the game for 90 minutes, till extra time and beyond. #discos

Just ensure your game formation starts from behind with your goalkeeper and defence. Solid foundation. #discos

From afar and every angle, you can identify good defenders. You can also see a great attack when they score. #discos

It's very difficult to score in the game so you make your decisions based on your attack, you would lose the game. #discos

If the defence is good, the coach can close his eyes, focus & build from the back and the team will have a very good game. #winning! #discos

You can pack the bus with a solid defence and park the bus to beimmovable by any attackers. Just make sure the backline is good. #discos

Don't be fooled. You don't need to control the midfield to win the game. Just pack the back & ride the defence. #discos

You might get attracted to a team due to their attack that leaves opponents messi. But the strength of a team is in the solid back. #discos

If you attack in the game, you should not leave your back exposed. So move from the back, with a solid foundation. #discos

The team that concedes the least wins, so your defence is always more important. A good backline always trumps any frontline. #discos

Francis defended the point and pretty much won the debate with this statement and tweet.

a solid back is the winner @mightyafrican @abocco

Are you convinced? ;-)

PS: #discos is some hashtag supposed to be for a debate and discussion. Might choose another appropriate hash tag later.
