Why Place a Prop Bet on Floyd by Decision at -200 when the Over is -180?

Floyd Mayweather Jr is more than a 4-1 favorite to beat Shane Mosley in next weeks mega fight. This line just seems way too high. Shane Mosley isn't getting any younger and he's coming off of a long layoff, but he's still arguably the fastest and most powerful fighter Floyd Mayweather has ever faced. Not to mention that Shane's last fight was a masterful performance, although Margarito was tailor made for Mosley. Don't get it twisted, Floyd Mayweather would have done the same thing to Margarito and so will Sergio Martinez if there is ever a rematch. Margarito can't box. He should just stick to the Cotto's and Cintron's of the world. With that being said, the prop bet of Floyd Mayweather by decision over Shane Mosley will most likely be in the -200 to -250 range, which is not crazy considering Shane Mosley has never been stopped and Floyd is just not a big puncher. But why would anyone risk a -200 to -250 wager if you only had to risk -180 for an outcome that has a greater chance of hitting? The over/under for Mayweather-Mosley is 11.5 rounds. Now, if you take the over and Floyd wins a decision, you win. If Mosley wins a decision, you win. If there is a draw, you win. If the fight is stopped at 1:31 in the 12th round, you win. The only way the prop bet of Mayweather by decision has any advantage is if there is a technical decision which is rare and completely unpredictable. A technical decision usually happens when one fighter is badly cut by an accidental head butt and the fight goes to the scorecards. If anyone tries to predict an outcome like that, they're not Brandon Lang or Nostradamus, they're just insane. Odds On Action has placed $50 on the fight being Over 11.5 rounds at -180. Please advise: I did have a dream that Floyd Mayweather got KTFO by Shane Mosley, but let's just hope that was only a dream and not a prophecy. Yes, I dream about boxing. It's pretty lame.
