Because there isn’t really a fucking choice. If you cannot see that there is zero reason anyone else should try and spend the time to explain it.
Yes there are other organisations.
Yes they don’t have to sign the contract.
Yes they are not forced to sign the contract.
The issues are the UFC for a long time had a very solid monopoly on this market and although it may be shrinking slightly everyone still wants to be apart of the biggest and most recognised promotion in the world. Everyone here knows for a fact if any fighter paid money they don’t have to a lawyer to look over a contract for a promotion they’ve worked 5 - 10 years to get into.. then found the balls to say ‘sorry Claude 4.1.2 take that out and I’ll sign’ knows damn well the UFC would laugh on their face and tell them to get the fuck out of their office or cut whatever they just offered them in half and let them sign.
You’ve worked 10 years, you just got your opportunity. Are you going to piss it up the wall? It’s a game they are forced to play with little to no other choice. It’s the one path to getting known and getting paid, it’s just not a fair path. You are as known as the UFC wants you to be, they create the story at every angle, they create the stars.
