I don't think Tony will take the Riverira fight,it proves nothing!I'd like Tony to fight Zab too and when he knocks him out,he will have the name on his resume that he needs.
There are also guys like Clottey,Williams(whom he took to war in sparring)and Quintana(who has been mentioned as a possibility) but I don't think he willget anything from beating these guys,it'll be like the Cintron fight. EVERYONE hyped Cintron as this killer,as the new tito and when Tony beat the shat out of him,everyone says who is Cintron,he was overhyped etc etc.

Vargas is tough but Tito annihilated him and almost ruined him,ditto Oscar and he has never been the same. He does not excel at anything,he's slow,flat footed,and takes alot of punches and the amount of leather Margarito would throw at him would swamp him!
