Agreed!! Brook at present is not "marquee" enough to be next in line for Floyd..but a win over Khan could be sufficient to earn Kell a fight with Mayweather. On the other side, Khan is a big name, but has done nothing at 147 (expect beat old man Collazo). Were Khan to beat Brook he would almost certainly get a shot at Mayweather. Khan-vs-Brook is a fight I would happily pay to see!! Two prime UK fighters, who genuinely dislike each other, contesting a genuine world title with the winner looking good for a fight with Mayweather!!! That would be a huge UK Box Office fight!! Brook-vs-Khan makes so much sense it probably will not happen!! Khan is busy trying to circumvent all credible opposition in his quest for a Mayweather fight, and Team Brook may choose an (on paper) easier option. Knowing Fast Eddie (Brook's Promoter) don't be surprised if next up for Brook is Bundu or Bizier!! Followed by a mandatory against no1. Ranked Dan Ion (Christ!! The IBF WW Rankings are a ****ing joke!!!).
