Er no. Ruiz was an old broken down shell of the fighter he once was and Chisors, whilst no great shakes himself, at least has the virtue of youth on his side. He's also never been knocked down before in his professional career, whereas Ruiz was knocked down several times prior to the Haye fight, most notably against Golota and James Toney. Not to mention stylistically they're quite different. And so on.
Really quite a silly comparison.
