If he can only go two hard rounds, then no, he shouldn't be at 145 anymore. The difference is Edgar has proven time and time again that he just doesn't gas. It doesn't matter how much damage he takes. Besides, what fights are left for him anyway? Llamas? Zombie? Win. Win. No thanks. Aldo-Zombie would have some entertainment value to it, but let's face it, Zombie would get trucked. I mean unless that Pettis fight comes to fruition, why not move up? Vacate the belt and try to conquer 155. What's he got left to prove at 145? At least then we wouldn't have to hear about how tough the cut is for him every fight.
