Ortiz, just a better boxer and mover, defense, speed. Tough fight but a 10-5 or 9-6 UD none the less and a compelling technical fight
Ortiz would decisively defeat Chavez ala Frankie Randall only more so and in Chavez' lightweight prime. It would be a tough fight, of course, but Ortiz would be able to take the best Chavez had to offer and be more effective in delivering his offensive weoponry.
