For people who think Tyson couldn't cut off the ring they are wrong:
"Now lets have a look at Tyson. Tyson became the youngest heavyweight champion of all time in 1986 at age 20. Tyson fought behind a high guard in the peek-a-boo defence style. He would lunge in with hooks which often knocked his opponents out very early on. Tyson had a great chin and a huge neck to absorb punches, he had great head movement, great power and great speed, he was very aggressive and could cut off the ring very well."
