Well, that not fair. PBF got help with that KO. Pillar of the post gave him a hand when Hatton's face bounced off of it :yep :yep :yep . Your right about the left hooks. I truly believe he wanted to make a statement by knocking Hatton out instead of outboxing him. This way there is no excuses of a robbery by the judges.
Probably because it's more exciting to watch Bette Midler concerts on an endless loop than to watch Zahir Raheem fight.
