Eh, Oscars power didn't really carry at weights around 160 lbs.
I think 200 lb roided up Belfort might be able to handle him at this point.
Oscar has also taken terrible care of himself.
Belfort would be countered all night long. After the first round would give up as usual and Oscar would win an easy decision. Seriously, check the video, he looks better than Vitor. At least in training.
