The best thing for both Mundine & Green, is to forget about each other. A rematch would be a big step back for both of them, Green keeps saying the public want to see it, me, nah, I'd much rather they left our shores and made a name for themselves outside of australia.
For Mundine, he's too old to be going down weight divisions, he should just focus on Super Middleweight.. pursue Pavlik, Bute, Martinez or Sturm. And for god sakes stay overseas, don't come back home and fly in Manfredo or Miranda or some other middle of the pack fighter. Pursue a big name, somebody with credibility.
And Green, well, he's gotta do the same. Fight Dawson, Tarver, Pascal, Branco etc. Offer Hopkins a 90/10 purse split to get into the ring, do it on his home turf. Give him everything he wants. Bill it as the man who beat Roy in 122 seconds vs the man who beat Roy in 2160 seconds. If he backs off then, he's an absolute coward..and Green will have the bragging rights.
