Im not real big on fighters paying managers or management teams large percentages (or any percentages for that matter) of their earnings. For the most part, the fighters should be able to handle their own contract negotiations and manage their own money until they reach GSP or Anderson Silva kind of money, at which point handling that kind of stuff can become a bit of a chore. These MMA managers for the most part are not doing jack shit that the fighters couldn't do themselves. It's generally a rip off. They are an unnecessary middle man.
