If he can't beat Vitor he can't beat Silva, so what's the difference? And don't say money because a true fighter doesn't think like that.
You don't think they are thinking about paychecks? The amount of times fighters have done/said things to protect their money or make more money is crazy. Fighters are constantly talking about it being a job and protecting their shots. Or saying so and so would be big money.
They may be true fighters, but this is their job now.
