For GGG....Guerrero, Rosado (and Rubio) are perfect. All solid..two of them are prime and somewhat close to earning a shot at 154 or 160...but most importantly for GGG, all three of them have decent regional following. Rosado and Guerrero will bring fans on the east coast so that's good. IMO, this is how GGG can ensure he stays on HBO and garner a quick following...by going anywhere and fighting hometown guys and picking up fans asap.
Get some steam behind the next MW title fight with Geale hopefully, and then put pressure on Sergio once he brings some monetary benefits to the table.
Fernando looked alright in his last fight, I think his defense has looked a little more solid than before even though his opponent was older. Could turn into an awkward fight and might be something GGG needs before a potential Sergio fight
