I will go with Youngblood on that one; They are trying to promote the fight so they have to say the usual routine stuff, will break records, incredibly fight, perhaps one of the best of the century and so on.
Personally, I am not insulted by it... neither am I naive enough to buy their predictions, I would say that this fight will turn more around 372 000 buys, maybe 400K if they are lucky but not more than this, not for Mayweather or Marquez.
