This is a fight I'm quite sure would end in stoppage. I'm just not sure if it's Zab early or Ortiz late.
I think Ortiz is just too physical and too strong for Zab. Ortiz has quite an offensive arsenal and Zab has terrible defense (his only defense is his offense really). I think Zab would get KO'd.
Zab would beat Ortiz IMO he is the better boxer, puncher, and athlete. Not to mention mentally I dunno if Ortiz would last if he were to get caught by one of Zabs left uppercuts.
I wouldn't be surprised if literally anything happened in that fight. These are not predictable guys.
It would be a very good fight and with Alexander already tied down to a title defense, and Khan doing who knows what Ortiz-Judah each need another big win to get into the title hunt. Fighting each other could do that, and the winner will surely move up the ranks.
