Brook I like Rees but I don't think he can outpoint Broner and he lacks the punching power to KO him. Burns on the otherhand, could beat Broner.
Would have to be Rees... easily... I'll be in the minority here but I think if Murray beats Martinez it's less of a shock than if Brook beats Alexander.
forgot about martin, and thought the OP was about andy murray winning aussie open in terms of the odds: brook is best priced 13/8 murray is best priced 6/1 rees is best priced 16/1 would have expected peoples answers to follow something similar to this
Clearly Brook from this list. But I expect them all to lose, with Brook having the biggest chance of pulling the upset. edit: I think this tells the story; Adrien Broner (1/33)Draw (40)Gavin Rees (16) Sergio Gabriel Martinez (1/7) Draw (35) Martin Murray (6) Kell Brook (13/8 )Draw (25)Devon Alexander (4/6) edit2: I see someone already put up the odds
