A few things have to happen for Caceres to win this fight.
He has to fight with extreme confidence.
He has to start off very strongly and get in Faber's head.
He has to fight tall on the feet and keep Faber at distance.
While he has a good guard, I can't help but feel that Faber's seen and experienced everything a fighter can on the ground so it's unlikely that Bruce Leeroy will catch him in a sub off his back, and he's extremely unlikely to get Faber on HIS back or take his back unless through a knockdown.
For mine, his only real shot is a flash knockdown > back take > RNC or jabbing his way to a decision, using lots of head movement, footwork and SPRAWL.
