Let's take a fantasy Salvador Sanchez from the Gomez fight and upscale his weight to 135lbs, then have him fight two Duran's: The DeJesus 3 Duran The Dejesus 2 Duran Can Sal beat em both? does he lose to both? does he lose to one only? who wins?
Its impossible to pick Sal over Duran when we dont even know how he'd fare against the greats of 130, much less THE greatest at 135.
Are we making Sanchez a natural lightweight or making him move up to fight Duran? Either way I'd say he loses, but if hes moving up it might just be a stoppage loss
