The Jab

[jms]

Feet to wide and of balance, His speed got him out of trouble.

In my opinion the other guy's head coming so far forward was what stuck out. No way Tyson should have been able to reach him at all with that jab the way Tyson was moving. How much faster does a fast guy get when you stick your head in his range every time you jab?

Edit: Second gif, good timing. Tyson steps in with his jab as the other guy is stepping his right foot. Since that guy also has his head forward, he can't get it out of range fast enough. If he had better positioning in the first place, he could have stepped forward and still not have moved into range.

Besides all that, Tyson is trying to get those guys to open up and throw at him anyway. His jab shouldn't be viewed as an attack, but as an invitation for his opponent to (attempt to) counter.
