MMA/boxing whistle blower

Pulp Fiction is such a great film. I was wondering if you guys have any film theories that perhaps Quinton Tarantino or any of the cast knew Don King or Bob Arum, Ving Rhames did go onto play Don King. Inter working politics of boxing always intrigued me, I was wondering if real live boxing was rigged the same way in Pulp Fiction and Quinton knows this first hand because he personal knows Promoters.
