Re: How come short fighters no longer use the bob and weave?
It's a hard style to pull-off, because it requires a lot of careful training and fitness. THAT's why it's rare in an age where most Western boxers don't come from such harsh backgrounds and have plenty of comfortable opportunities outwith boxing.
In places like Eastern Europe, the Phillippines, Latin America and Africa, you can still find plenty of people from very tough backgrounds who are willing to put in the tremendous work to make styles like the bob-and-weave or stick-and-move work.
The "jab-jab-grab" style is a better alternative for lazy Westerners, especially heavyweights.
