Who should Vanes fight next? A couple of good choices are J-rock, Harrison, maybe even Glen Tapia if he stays at 160lb.
If Rosado does fight Brook, that leaves Mora and Vanes as Chavez jr other choice. If not maybe Trout when he loses to Charlo.
Vanes is a good fighter. I think he'll do OK at 154 if he stays active. He's a step below the elite but he'll give them a tough night.
Vanes should push for the Brook fight, no matter the money. I think he would beat Brook pretty easily that would open up many options for him. May be a Wbc title shot at 154lb.
