As for his chances at 154? Well I'd say Quintana could give a good run against guys like Dz, Sergio Martinez and Daniel Santos (if Santos is still alive). I would keep him far away from Angulo...the body work of Angulo would eat Quintana up.
154 is wide open, it used to be a big division when Oscar DLH, Shane Mosley, Fernando Vargas, and Winky Wright were at 154.
I agree, especially about the Santos status :yep but seriously, I too think Angulo is a very rough match up for Quintana and someone he would eventually need to fight.
