I think Ncita's quickness and his southpaw stance would really bother Barerra, but what I don't like is Ncita's lack of real serious power and his sometimes shaky concentration... I think he starts well and is probably ahead after 6 rounds, but Barerra's bodypunching takes it toll, slowing him down and tiring him out... Barerra takes over in the second half and either stops Ncita late or wins a decision thanks to a knockdown
That's how I see it as well. Ncita has all the tools to give the young Barrera all he can handle but his defensive lapses and tendency to brawl a bit too much would allow MAB to reel him in down the stretch.
