Foster comes in to box and move. Watch Frazier pre-cut the ring, establish range with the jab and then close the distance with the hook. From the first one that's landed he takes Foster out of his gameplan. Around twenty seconds Joe lands the "long hook" and from that point on Foster is basically descending from a box mover to a runner in incriments. This is how you deploy a swarming, stifling style, this is how you do fast pressure. An attacking machine.
