First he should destroy Bonnar to give him 3 losses in a row, then destroy Forest, then destroy Rashad and/or Lambert, then win a decision to Sobral (kind of a stretch but highly feezable), then hang tough with Tito and lose a decision, then back to Sobral for a rematch, lose, then back to Forest who will be 8-2 by that time. That's what I think's gonna happen just my prediction though.
Edit: 8-2 in the UFC in regards to Griffin^^
