Tumenov for having better defense, chin and counters.
Martins for being more experienced, underrated (has great tdd) and more polished against a raw brute still developing. Betting against the new Dagestani prospect doesn't feel right though.
Coin flip on Yair vs Hooker; Hooker is a prospect like Yair; both are offensively talented with Yair being the quicker striker. I favor Hooker with 4 in of reach, but never bet against a guy like Yair who's desire to win is on another level.
Pettis' crutch is he's over confident, Cariaso's crutch is he gets held against the cage and outwrestled. Pettis is young and will improve, Cariaso is far more experienced, but is getting older. Cariaso should win, but Pettis has a chance at stealing the points. Coin flip.
