Terence Crawford's (29-0, 20 KO) dismantling of Viktor Postol (28-1, 12 KO) has many explanations.
The most striking observation was that Postol, who outsized Crawford and Lucas Matthysse, fought Matthysse moving backwards but did the opposite with Crawford. This is largely explained by Matthysse's reputation as a heavy-handed puncher. The other reason was Crawford's superior foot speed that allowed him to control the outside angle on Postol, forcing Postol to follow him around the ring.
Crawford's disadvantage of reach was not so bad that he could not capitalize on a slower and clumsier Postol once he committed. Normally Crawford is vulnerable to straight right hands from southpaw – his shoulders too square and reflexes too slow, even with a size advantage over smaller opponents. When the speed of his opponent was removed from the equation, Crawford was less square by controlling the outside angle, which nullified the right hand of Postol – Postol is not a prominent left hooker – and allowed him to extend with his straight left hand towards Postol's mid line. With good extension, Postol being too slow, Postol continually moving forward, Crawford could not miss with the left.
Given the events of last night, suffice it to say that Crawford's use of the southpaw stance – which is less natural to him than orthodox and thus causes him to sacrifice some of his power – is not only about using his jab on smaller opponents. Crawford additionally finds himself more accurate with straight power to an opponent's mid line. when he is certain of where his opponent will be and his opponent's defense is lacking.
Contributing an observation by the truly non-revered HBO commentator Jim Lampley, perhaps by using his lead hand to control the lead hand of his opponent, Crawford is better able to see and anticipate what is thrown from the other side.
Nonetheless, these things are offset by speed, which Postol did not have. Cutting off the ring was also very uncomfortable for Postol who truly preferred to keep his shoulders at an angle to his to position his jab and right hand – indeed, Postol is not a hooker. For even when Postol was close to Crawford, he seemed reluctant to throw, the positioning and distance not feeling quite right.
But that was also because Postol's lack of punch resistance, now accounted for. Indeed, Crawford managed to score two knockdowns in the fifth round. While the first knockdown was a rabbit punch from a counter right hook, with a slight push, to the back of Postol's head in the opening seconds, the second knockdown was more legitimate and resulted from a counter left hand to the chin later in the round. Postol stumbled around the ring and his glove appeared to touch the mat before he fell into the ropes. On several other occasions, Postol seemed hurt by Crawford and attempted to retreat to the other side of the ring as if he did not want to engage.
Crawford won a landslide unanimous decision, Postol only managing to be competitive for the first three rounds.
Bob Arum continues to show interest in making Pacquiao-Crawford. (Manny Pacquiao has expressed his desire to fight again in the fall of this year.) WBO welterweight titleholder Jessie Vargas is also being strongly considered for Pacquiao and had been even before he lost to Timothy Bradley last year.
