Agbeko has the tools to KO Darchinyan. If Donaire who is lighter fighter can knock Vic, how much more w/ Joseph who's been fighting as a bantamweight for almost 10 years. I don't think Vic can carry his power in the bantams. He's pushing his luck too far.
I didn't see Agbeko's last fight, but he has been in with 2 world class fighters, Luis Perez and Wladimir Sidorenko. He definitely is no push over, he was electric in his win over Perez; and apparently flat in his last fight. I think the inactivity hurt him in his last fight, he has fought only 3 times in the last 2 years, I think this will come into play in the Darchinyan fight. In that same 2 year span Vic has been in the ring 6 times with good to great competition (minus the Catubay fight). Vic has not only been more active he has been destroying very good to great fighters. Vic by late round ko or decision, but Agbeko is a very live dog.
