I think so too. I predict a war, Froch will look good I think because of Abraham's style, it will get very interesting come the business end of the fight.
Abraham obviously punches pretty hard. As for devastating..... erm, no Definitely not at super middle. He probably punches on a par with Froch.
You are paying far too much attention to meaningless stats like how long someobody gets KO'd in and who did what to who. It's not ABC. I think if you look at Abraham's knockouts and his style its obvious he's a big, big puncher
If you look at their respective twelfth-round knockouts of Jermain Taylor, and take the ultimate finishing shots at face value, Abraham's was indeed more devastating (although both got the job done). It's a narrow scientific sampling, but serves the point. They also have a common opponent in Dirrell, but due to styles Abraham wasn't able to catch Andre flush as much as Froch managed, so there isn't much there to compare. I'd say Abraham's power at 168 is currently inconclusive, but lean towards it carrying up fairly well from 160 (where he was indeed devastating - and not to gush, but maybe the hardest hitting middleweight since Jackson). Maybe 80% or more.
I was at the Dirrell fight and i had the feeling that at any given moment now Abraham was about to knock him out. I was on the edge of my seat being that i wanted Dirrell to win.
