Awesome, awesome thread. I'll definitely be coming back in here later.
"Good footwork" is a bit like "hands up." It seems like a sensible thing to say until you start to actually think about it. Unfortunately, lots of folks seem to think that quick feet are equivalent to good footwork, hence lots of people saying that JDS has great footwork, or Frankie Edgar. They don't have the most appalling positioning in the world, but guys like that rely on speed and aggression to maintain defense while attacking. Pettis really is something special for MMA, the way he works himself into positions to land his strikes and avoid his opponents'.
are you saying frankie edgar doesn't have good footwork
