Which is most likely the upset that can happen tonight, Ruiz KO Haye or RJJ KO Hopkins?

Of course, both most likely will not happen, but I am just wondering which would be a bigger upset at their points of their careers. Hopkins has never been knocked out before. Haye has been knocked out once, but he is much younger than Hopkins and at the peah of his prime while Hopkins is waiting for his age to catch up to his body. Hopkins is 45, however, and Haye is a rising star still making his way to the ladder of the heavyweight division. Hopkins has the superior resume and is an HOF.
