On to the main point, you cant really tell the out come for something as preposterous as p4p "what if they're the same size".
@ the time, Toney was the undefeated 168lb champion and sitting on top of most P4P lists. I'm sure that I can find something to knock most of Manny's opponents also. That said, @ the end of the day, Jones' shutout over Toney is more impressive than any win on Manny's resume...
