JDS needs to KO Mir clean, if he follows him to the ground, Mir will take a limb. I see Mir even playing a little possum and dropping at the first tap just to see if he can get JDS to be overconfident and leap into his guard. If not, hopefully Mir will be smart enough to jump guard, because theres no way he'll be able to take him down otherwise. Its an interesting match up honestly, Mir is the most dangerous jitsu HW in the world and you can never count him out.
Hopefully Cain puts a huge beating on the Ortiz style head of Silva.
