Ortiz would KO Zab in about 5, Judah can't fight going backwards, And a 160+ pound Ortiz would stalk and overwhelm little Zab.
Very tough match up to pick a winner . I would say its a toss up ,its either Judah by midround TKO or Ortiz by UD/late stoppage . Would be a hell of a fight for the first 5-6 rounds though .
Zab is one of the few fighters who can match Victor in the heart department and throw into the mix he's got a terrible chin you're looking at Ortiz TKO within 6 rounds.
