It's simple........romero needs an opponent with a name.
Silva asked for romero and has a name.
If Silva somehow wins, it would be epic.
If romero destroys silva, then the hype for the eventual fight vs bisping will be much bigger.
Romero's impressive physique has you guys all in a romo fap tizzy and ready to crown him champion when he's shown plenty of weakness like his inability to finish off a clearly KO'd Jacare.............or his pathetic performance that had the crowd booing him the entire first round before being KO'd by Feijao.
Silva is still dangerous, has a name, and remember that he asked for this fight.
Now the opportunity is there and UFC will shuffle some scrub to romero instead.
