Exactly, and the jabs thrown by Sonny Liston are all while he is moving to Ali's right. Should have been able to set up Ali for the over hand with that, but Ali shows amazing ability to comprehend his opponent's range with this.

Also, not everyone can tilt their head to the left. It is more impressive than most people know. Head movement is something you do not see a lot of in MMA. It sets up counters, feints and combinations. I wish more fighters do what Silva does, which is actually engage exchanges with head (in his case full body) movement. It is difficult though, because jabs, crosses and hooks aren't the only thing coming at you.

Also, we must remember boxing and MMA are completely different when it comes to head movement. Boxing is subtle and quick, hence Ali "simply" having to flick his head from side to side to dodge a punch.

Griffin throws bombs and the left hook is thrown with so much advanced knowledge of it coming, Silva can dodge it easily and counter.

One more thing, notice Silva is never out of position for a potential takedown/tieup. Just absolutely beautiful and both fights should be recognized for their amazing ability in their respective art.

EDIT: Not Sonny Liston, it is Ernie Terrel. Thanks NothingSacred for the correction.
