I feel the difference in this fight will be combos. Pettis is way too comfortable as of late just throwing a single punch or kick with no real follow up. Cerrone on the otherhand has been starting to mix it up better and better. Pettis leaves himself fairly unguarded after throwing a punch or kick as well.
I see a Cerrone decision win based on more blows landed, but Cerrones face to look worse as he shows damage very easily.
