According to
this report, the two sides finally agreed at a catch weight of 143. That single pound may not seem like much, but it is. Mayweather is always in top condition, but will needing to drp that extra pound be a factor, the way the low weight was a factor for De La Hoya against Pacquiao. I don't think it will, but you have to at least consider the possibility.
It's basically impossible to pick against Floyd Mayweather, but Marquez is the best all-around boxer Mayweather has fought since, well, ever. And Mayweather has the X-factor of a 20-month layoff coming into this fight. In the end, I think Mayweather is just too defensively slick and has too many skills and ring smarts to lose, but I'd rate Marquez as a very live underdog. If he wins, it owuld be an upset, nut not really a shocker.
With the winner of tonight's fight slated to take on the winner of Mayweather-Marquez, this is shaping up a good year for big fights. I'm really looking forward to al of these.
