Of course it's Floyd's fault!
Isn't going around Top Rank's back for the Pacquiao fight in the first place merely the tat for Arum's insistence that he just didn't know who represented Floyd and his refusal to answer Schaefer's calls on the fight? If Floyd and Golden Boy are one and the same it makes Arum's public statements earlier this year about the May 5th date look even more ridiculous
than they already do.
Of course all of the above accepts your absurd shifting of the goalposts and your attempt to bring in something completely irrelevant to somehow justify Arum's disingenuous offer. Likewise, Mayweather's offer to Pacquiao could not actually be accepted without Top Rank signing off on it, something that makes your phrase "go around Top Rank's back" an inappropriate description.
