Kovalev didn't TKO Hopkins, so that means he can't take out Froch? What kind of lame logic is that? Hopkins is a wily old veteran who's never been stopped. He knows every trick in the book, and his game at this stage is all about survival. He'll retire without getting knocked out. Froch is a come-forward, tough brawler. The type of style that either gets the opponent in trouble.... or him in trouble. Not saying it's a foregone conclusion, but I can see where Kovalev could foreseeable take out Froch.
