I picked Oleg to win also, the thing to remember about rematches in boxing. If all things are equal the first fight the rematch will end the same way only usually faster and more impressive for the original winner. Now the exceptions to the rule is say fighter A losses the first fight because he is sick with the flu or injured in someway or is the victim of piss poor judging which is usually the case .He can win the rematch a fight that comes to mind is Fenech - Nelson I Azumah was sick with the flu and got a draw in the first fight , in the Rematch Azumah was healthy and won the rematch very impressively.

The main thing is if both fighters are at their best in the first fight , nothing should change in second fight if both fighter come in correct. i forget the exact percentage but its like 70% of the time the fighter that wins the first fight is going to win the second fight. which leaves 30 % for the other guy.. its just mathematics .
