I really doubt he will become number 1 but he could get close to it if he blows Manny away by KO, definitely top 5.

If he beats Manny on decision I would put him up to number 6. He'd have to beat him convicingly to get in a top 5 spot imo. #5 is Mosley and he blew Margarito away to get there.

If he beats Pac and Marquez he gets #1 though, people can say what they want about size but there isnt much in it and if you win against #1 and #2 you deserve it for sure.

Just as interesting is where would Manny go if he loses? Can he still be #1?
