Quinton Jackson doesn’t have the best history with managers and coaches. His current one, Tiki Ghosn , knows this well. In his 18-year relationship with the ex-UFC champ and current Bellator star, he’s seen a lot of faces come and go. Some have filed lawsuits on their way out. Jackson (37-13 MMA, 4-2 BMMA), 39, appears to want his latest manager to stick.
