on the importance of strong Defense

...Most boxing experts will concede that a great defense usually beats a great offense.

in an article about Tyson on Pacquiao.
Tyson was asked about the contemporary fighter he most enjoys watching and his answer was quick and definite. "No fighter looks more sensational than Pacquiao looked the other night," Tyson said, without hesitation. When co-host, Wiley, interjected and mentioned the name of Floyd Mayweather, things took a surprisingly serious tone. "That shows you are a neophyte in boxing, you know nothing about boxing," Tyson told Wiley. "No one said who was better, I said there's nobody in boxing that looks sensational the way Pacquiao looked against Rios...it was masterful, the side movements, Rios couldn't get a punch off…masterful boxing, like Willie Pep, it was brilliant." Kellerman and Wiley would move on to other questions, but the former heavyweight champ's fondness for Pacquiao and Pacquiao's ring style was quite clear. And the awe and respect for Pacquiao's style is, really, what's at the heart of the Mayweather-Pacquiao debate. Pacquiao is an offense-minded fighter with a crowd-pleasing style. As such, his ability to shock and awe audiences depends greatly on who stands in front of him in the ring. A flat-footed brawler is ideal for Pacquiao's style while a smart, defense-minded counter-puncher is not. On the other side of the debate is Mayweather, whose defensive style and sharp counter-punching is based on nullifying the intended shock and awe of offensive fighters. Personal preference plays a great role in whether someone backs Mayweather or Pacquiao, but as even Tyson was quick to point out, this isn't necessarily about who is better. Most boxing experts will concede that a great defense usually beats a great offense.

So what is defense?
4 ways
1. No defense. Tough, eat punches. Able to take strikes
2. Block punches
3. Evade. Don't get hit. Movement and Position.
4. Offensive. Attack before their strike reaches you at power. Don't be at the position that they initially launched their attack. Don't be where they want you to be.

Point? Don't get injured? How do you get injured? By getting hit. How do you Avoid getting hit? Block it. and if you have the Awareness of it coming even sooner, get out of the way = movement and position.
