I saw it a couple of weeks ago, and what Freddie Pacheco said was along the lines of "Holyfield was a 25-1 underdog,but just before the fight it went down to 6-1" and then Czyz said "Did someone know something we didnt?"
Its boxing so who knows...... My uncle was in Vegas for the Sanchez-Gomez fight and he planned to bet on Gomez. Jose Torres, the former Light Heavyweight champion of the world, was there too and he told my uncle not to bet on Gomez because he felt Gomez did not look right for that bout. Torres knew something we didnt know. The same could be here too.
I am going to go back to something my late Grandfather once said to me about that (quoted the best I can from memory): "The wild odds shift had more to do with Holyfield than Tyson. Tyson was a wide favorite against Holyfield early, because gamblers knew there had been something wrong with Holyfield in some of the fights leading up to the Tyson fight, and it even was apparent in training. Then, suddenly, Holyfield seemed okay again, for whatever reason, which was also apparent in training, so the odds narrowed significantly." -Djanders/shaysonya.
Wasn't the real issue that he'd had hep-a and then he finally fully recovered? He'd been Evan Fields well before he fought Tyson, so that isn't it.
People started betting on him and the odds came down. Holyfield didn't look so great against Bowe (third fight) and Czyz, and nobody thought he'd win against Tyson, so the oddsmakers set the odds at 25-1, so people would bet on Evander. It was hard to pass up. So a lot of people put money on him and the odds came down. That's how it works.
Jimmy Vaccaro opened the odds at 27 - 1 at the Mirage, Tyson vs Douglas and he started taking action. The fight went off at 42 - 1. It happens
The odds were mostly based on their reasonably recent fights. Tyson had looked awesome, Holyfield ordinary. Also, Tyson was such a short favorite that to entice money out of the standard punter they had to offer "juicy" odds on Holyfield. A lot of people wanted Holyfield to win as well so why not get on those juicy odds. The money kept coming in on Holyfield but unlike the norm no late money was coming in for Tyson as his odds eased out a little. The bookies were destroyed in this one which was a welcome change.
