There has to be more to this contract then a just 8 fights or whatever. Maybe Eddie signed an 8 fight deal worth like 300K a fight, got 1 million dollar bonus, maybe handed a couple sponsor deals worth a few million over the course of his fight deal, and maybe he has a position within ONE at the end of his career work "x" amount per a year with a guarantee 5 year job or something. It's the only way I see Eddie getting anywhere near 8 figures.
To me, Eddie is worth about 200K to 300K a fight for pretty much any org. With the UFC he deserves a PPV cut. I just can't see or make sense of any org paying him more than a guarantee 400K a fight. He just isn't going to bring the business in to support paying him more.
P.S.: I think ONE is blowing smoke up Eddie's ass about signing big stars in the very near future. I can't think of one big star that is even a free agent to sign. Sage is by no means a game changer. Maybe Lesnar they been talking to behind the UFC's back. But once again not a game changer over all. A shock, yes. Hey, they also just said they'll do a 100 show in two years or whatever. I don't think they have get gone a whole year without cancelling at least a show or two.
