I think Brook was waiting on Khan... but Khan was waiting on Mayweather... and Mayweather was mulling whether it will be Pac/Khan or Mundine (hehehehe)... so, Mayweather's pussy ass dithering is at the root of all of this.

Brook should just let it slide. Khan can't be out of his sights for too long. Fight Gavin, Bizier, Ion or some other easy bout. It may be a blessing in disguise for Brook.
