Bika's style is so aggressive/wreckless that it's very hard for anyone to have much of a gameplan against him. A fighter who doesn't like getting hit like Mundine, and who would avoid getting into a war to win the fight, would give up against a Bika that would have little to fear from turning it into a brawl. In every fight in which Bika's brawled (e.g. not the Bute fight), he's done damage, even against power (v. Codrington) or skill + speed (v. Calzaghe). Bike would give everything against Mundine; Mundine wouldn't, against Bika. I think it would make the difference even if Mundine lasted the distance, these days, with Mundine getting hit more easily and bing less willing to dig deep for a win.
Mundine has amazing natural gifts, and is underrated for his timing, it is fantastic. But I think I'm the only one who counts his vision as a variable here. He has looked uncharectaristicly **** since he ****ed his eye. To go from the sensational belting he put on Sam Soliman in their second fight to the scrappy decision he took over some joker named Crazy Kim (Copping a knockdown i the process) is just unheard of... The difference is massive. 2 eyed Mundine wins by lopsided decision, a scare or two along the way. 1 eyed Mundine starts okay, but is eventually bullied, bruised and possibly stopped in the later rounds... I'm calling it as Bika by late TKO.
Mundine is really on the slide and i wouldn't be surprised if Bika caught up to him in the later rounds.
