Why no interest to land a Pac fight?

Why no desperation to land a Pacquiao fight for those 130-147? I don't get it. Too have Floyd or Manny on your resume is like having Ali or Duran on it. From the perspective of being a professional boxer, how could you not want to have that fight enshrined in your legacy? Sure we can talk about promoters and such "getting in the way" but the truth of the matter, these are grown men who can will a Pac fight into reality if they truly vied for it publicly and privately. Beyond that you have all these "free agents" under Haymons advisement who, from what were supposed to believe, can do whatever they want. Putting Khan aside, considering he's already made his bones fighting big names throughout the Pac era, I'm referring to Danny Garcia, Mikey Garcia, Ryan Garcia, Loma, Spence, Crawford, Thurman, (I guess Broner's ship has sailed), and other top level guys I'm probably leaving out. Sure I'll concede the notion that perhaps Pacs camp don't want to face Crawford but where is the passion and hunger from the others? Perhaps this is a retorical question I'm asking because imo they think they will get Vargas'd or Mathysse'd. That is beside the point though. A loss against Pacquiao doesn't make or break any of these guys career. Was Iran's career in the *****ter after Duran? Was Malignaggi's after Hatton? And how about Pacquiao's after Morales I? No, no and no. These guys trying to be the next best thing around 140 are kidding themselves if they think fighting Manny Pacquiao wouldn't progress their career. Well maybe it wouldn't if they got blown out which maybe might be the thinking behind pretending he's irrelevant.
