Naz under-estimated how relentless MAB can be on the attack. I also don't think Naz or Emmanuel Steward thought Barrera could jab as good as he can. As for Naz's style, he had already strayed from true boxing, and was just trying to look pretty. I seriously think, both Manny and Naz thought Barrera had aged, or slowed, and Naz could just catch him and Ko MAB. However, they were wrong.
