don king literally ruined people's lives, he's in a category of his own. arum put on big fights when there was really nothing left to do, and even then did it reluctantly. he's the definition of "letting fights marinate". i always felt like hearn was actually trying to get big things going in the sport, rather than just talk about it.
i'm not naive enough to think he hasn't done shady shit, but my point is that as far as promoters go, he seems to be the least shitty one, both as a businessman and as a person.
