is Arum and Don King on threat?

For increasing numbers of self promoted boxers? I think Pac and Cotto are going to be too big for Arum to handle. and now more and more boxers are self promoting and going to team up with other self promoting boxing. I remeber once people critize Pac for not joining GBP. But Pac got in his Solis fight more than what Barrera and Marquez got for fighting each other. As for Don King he got Mike Tyson a title shot just as he left prison. even King and Arum take alot of money but it seems like sometimes they know they job. But those promoters will leave out the fight to the garbage if he finds he is not worth it.
