Andre Berto is the most impressive of the talents ive seen. Ok his defence can be lackluster and open and he can make many mistakes....but at least theyre throwing him in with tough fighters who can crack which is testing him already and will ultimately make him learn quicker and a better fighter becuase of it. He has the speed, the power, the array of punches and obviously the determination to be a very good fighter....just needs to iron out a couple of flaws, which im sure he will, and he will be a force for sure. I do not think too much of Kahn right now becuase he seems to be fighting people who get KO'd after one hard punch and are scared of him.Im not saying Kahn doesnt have the talent, becuase he has tons of it, he just needs more tests against better opposition before hes a master talent many think him to be already. Chavez looks impressive from what ive seen aswell.
