Your memory is just as bad as biface! The first negotiations failed, that contract was no longer valid obviously, unless they had a time machine they could hop in and travel back in time. Since the Flux Capacitor has not yet been invented, sadly that was not an option. Instead they offered to fight Floyd, two different times, and each time Floyd wasn't even willing to negotiate, stating he was on vacation or not thinking about boxing. Others attempted to negotiate on Floyd's behalf including Richard Schaefer, Al Haymon and Greenburg, all of which agreed to the terms team Pac laid out, but unfortunately Floyd wasn't on-board.Thus Pac fought other opponents instead.
Here we are in the present time and Pacquiao still remains he is willing to take the tests and that he wants Mayweather next, assuming they both win their fights.
Did you follow all of that or do we need to go over it again?
