I don't care what anyone says about Young Chavez....he's got the blood line of one of the all time greats and he's going to be champion. I wasn't sure about him until after he's shown great improvement with Roach, but from how he has filled out and what he's shown in his recent fights...he's gonna be a problem at 154 or even 160.
I don't know about all that but he's definitely talented and has got great physical dimension for 154! So all the physical tools are there and from the looks of it his skills are coming along just fine.
