Just basic style match up you'd have to favour AA. Pressure fighters don't do well against Punchers. Not too many p4p better punchers then AA. Junior has a great beard but you could see Sergio's punchers were affecting him last night. If Sergio can hurt Jnr AA would probably kill him. Chavez could box well enough to probably lose a UD but he couldn't box well enough to win and pressuring the whole fight would be a huge mistake.
bend over at the waist and walk at abraham basically at eye level with him (basically what jr does) and then start counting. see how far you get before your in the dressing room asking what happened. abraham isnt even that good but blocking his power shots with your face is a good way to get seriously hurt.
I actually believe martinez was able to shake up chavez with some straight lefts last night so yea i think it would be whos chin is better chavez or abraham.
Abraham is very, very passive, so there is the possibility to keep him busy by throwing straight hands in bunches (he just would fortify behind his high guard). Abraham's punches are easy to read for world class fighters, but i doubt, that Chavez is able to anticipate the shots, so at some time he's gonna get hurt really bad.
I think Jr needs to move up to 168 now, he looked unhealthy at the weigh in (imo) If he moves up to 168, I think he could very well beat Abraham. Would be an interesting fight. I think it comes down to how badly would AA be able to hurt Jr, because if he doesnt hurt him often or stop him, I think Jr takes a fair decision against him. just imo
