Very hard to say at this stage. Frampton has better preparation in fighting against martinez who is closer in style at this stage. I really don't know but it would be intriguing to see all 3 fight each other.
I see Santa Cruz causing frampton no end of problems backing him up Quiggs better defensively despite his knockdowns earlier on his career and so would be a stiffer test But Santa Cruz on form is a hell of a challenge for any bantam/super bantam
