Based on what I saw tonight, I think if Khan puts on the weight properly and doesn't lose his speed, he takes Berto.
Khan in one of the harder fights of his career. He can box circles around Berto, but Berto is going to bring the pressure with voluminous punches, with speed and power behind them.
Berto has the IBF title, Khan could face Berto early next year as his 147 debut, nice way to become 2 weight world champion for Khan.
Khan on points, hes gettin better as he gets bigger and the longer he trains in Roaches and Berto is decent but nothing more and isnt gettin any better.
The thing is that Berto will definitely land a couple of clean, full force punches to Khan's chin at some point. If Khan can get through those one or two moments then he will win a decision.
nOT SURE WHO WINS, Khan is the better boxer but Berto has the speed/power/strength to walk through punches and score KOs
Im going with berto ko, im not sold on khan taking punches from ortiz/berto at 147 and surviving, he seems to have convinced many people in the judah win though, if this poll was last year or after the maidana fight, the results would have been way different.
