Korobov, looked solid, however, not on the level of Triple G or Kovalev. He needs a couple of fights to rise to the level of the after mentioned fighters. He had his opponent on the ropes, but could not finish a a capable fighter. I like him, but the jury is still out.
On a side note. The black fighter in the main event, Crawford showed himself to be a formidable champ in the 135 / 140 weight divisions. He weathered the huge storm by Gamboa and KO'd him. Great performance. He carries himself well, ala Marvin Hagler. Low key and absent of TNB. I tip my hat to him in a great performance against a A level fighter who was giving him problems and rocked him throughout the fight.
