Mick really seem down to earth. Not much of a "fighter" in him. Imo Goossen seem's like the biggest ass of the bunch. I'd have to say King. He's made so many big fights and know's how to manipulate things to get it his way.
Goldenboy Promotions It's Oscar's goal for all prizefighters to have healthcare and retirement plans, at least that was what was written in his book.
I'd go with DiBella. He's the only promoter (other than maybe Hennesy) that doesn't seem like a total piece of **** and he seems to genuinely care about his fighters. All the other promoters seem to be complete pieces of **** who would sell out any of their fighters for the right price.
If you're going for how powerful they are than I'd go with Top Rank way before Frank Warren. Top Rank and GoldenBoy are the two most powerful.
