Israel Vasquez is a completely different proposition than anyone that Arce has faced before.

In his career Arce has indeed been faced with a fighter who has heart, passion and an iron will, surely.
But in fighting Vasquez he encounters a fighter with these attributes, some boxing skill, expierience and a size advantgae.

The trilogy with Marquez revealed that Vasquez has an excellent chin and body and his resolve is almost impossible to match. The movement of Arce will do little to disuade the diligent Vasquez and standing toe to toe with Israel would be career suicide I feel, as he simply could not be succesful.
