I too thought BOTH guys were taller than they are. I thought Miranda was a 6 footer.5'10 surpirsed me.
Abraham's not that tall, but he compensates by basically being as thick as a tank and having an extremely powerful back and shoulders, which is where that explosive one punch power comes from. One thing to remember though, is that it's impossible to truly be a jack of all trades. Abraham's heavy muscles basically ensure that he'll never be able to have the workrate of leaner fighters like Calzaghe or Pavlik because he'd gas if he were pressed to do it over an entire fight. To Abraham's credit, he fights with the exact style that fits him- the high guard, winning rounds by just throwing for the second half of them, and throwing big time countershots that carry alot of bang for the buck.
