No way. A better matchup might be Zab Judah versus Ortiz, Alexander, Kotelnik or Maidana. I think he could realistically beat any of those four on any given night.
Zab has a puncher's chance here. IF (and that's a big IF) he can land flush on Khan, I think he KO's him. That said, Zab looked so reluctant to pull the trigger on Saturday.
