Basing off of what Tim Kennedy said, some UFC fighters are broke because of the high ammount of percentage they have to give away to their camp. 13% gym fees, 10% manager, 10% coach, and 8% camp lodging (whatever that is). Thats 41% of their total earnings they won`t get! That`s just my opinion. I`m sure others will disagree. Anyways Tim`s interview is right here.
