That's actually pretty good fight. Tito, while much more skilled much better footwork was a welterweight. He was always too small for 160. GGG, punches like a light heavyweight is a very very solid middleweight. He is pretty straightforward though and somewhat predictable. I think Trinidad, could beat him granted he didn't get caught with something big early.
Tito by left hook. GGG gets hit too much, doesn't take a genius to figure out who wins that firefight.
Montiel is washed up at the moment and Tito was not. Moreover even current Montiel will be a step up for Rigo.
I agree but Hopkins was by far the biggest money fight available at the time...besides Mosley, of course.
