Ruiz was knocked the **** out against David Tua and down twice against Golota. The real question is, why are we even talking about John Ruiz?
It took prime David Tua to stop Ruiz. Whereas it took Lamon Brewster to stop Wlad. But, Wlad has mastered the Ruiz jab and grab tactic, and due to his hulking size has become even better at it than the Quietman. So, while Ruiz my be a pimp with a better chin, he is more vulnerable.
