I think by the time the WW tournament (if it is indeed a tournament) is over, the P4P list might look very different.

If by that time PBF does not even have a fight scheduled, he might not even be in the list at that time.

We also have some significant fights coming.

Hatton - Castillo Hatton should win but this is by no means a sure thing. Far from it if you ask me.
Winky - Hopkins Pretty much a picem fight.
Taylor - Pavlik Let's all hope it gets made. Whoever wins this will be top 5 easy because of JT 2 wins over Hopkins.
Calzaghe - Kessler Very close to being made. IF Calzaghe remains undefeated after this, he should be top 3.
R. Marquez - Vazques 2 If the fight turns out to be as actioned packed as the first one, you can bet that the winner will be ranked a tad higher than he probably should.

Also if PAC doesn't have a big fight soon he might slipp a couple of positions. P4P has always been as Merchant put it once a "what have you done for me lately, ranking".

Bassically, if Winky, Hatton, Taylor, Calzaghe and Marquez wins and if PBF keeps fighting and if PAC makes a fight with JMM or MAB by that time. The winner of the WW tournament might end up as low as 7th or 8th.

On the other hand in the highly unlikely event that PBF stays retired, PAC does not get a big fight, B-HOP, Castillo, Kessler and Pavlik win. Then the WW champ might end up as high as 1st or 2nd.

LOL now that's just crazy huh
