So what exactly was the deal between Silva and Belfort? Why was Anderson so angry as Vitor?
Years ago, when Belfort was going through bad times -- including the still unsolved kidnapping and murder of his sister Priscila -- he moved from Rio to Belo Horizonte. Silva, who was living in Rio at the time, dropped everything to spend time in Belo Horizonte with Belfort and help him along.
Their friendship remained intact afterward, but things have changed drastically in the last year. The reason? Silva reportedly was quite offended that Belfort would accept a fight with him after their history together. While Belfort saw it as a simple professional decision, Silva took it as a personal affront.
That further emphasizes their different outlooks on the sport.
Silva is originally a product of the famed Chute Boxe camp, where fighting is personal, and intimidation of your opponent is quite literally, part of the fight. They view the person across the cage from them as not an opponent, but an enemy.
"Anderson works like Chute Boxe," said Kallas. "He needs to feel excited for the fight. He needs to have an enemy. Anderson feels betrayed. He helped [Vitor] out and he was surprised that Vitor would fight him."
Belfort has never viewed it quite the same way. To him, the fight is a sport, a profession, nothing personal about it. That's why he's always moved from camp to camp, learning from different coaches and trainers rather than staying in one place.
Now Chael is the enemy and Silva is in kill mode.
