Why does it seem like Khan is the only option?

I feel like Amir Khan has been Floyd's only option for 6 or 7 months. What am I missing? You have Danny Garcia, Shaun Porter and even Keith Thurman and Khan has been Floyd's Only potential opponent. Even the Showtime guys last night were saying is this a potential match up against Floyd in September. I was like noooo the people dont want to see Floyd and Khan fight. Floyd almost fought Khan and that would have been his first fight at 147 but Floyd cant fight guys like Kirkland, Lara or Angulo at 154 which would be exciting and intriguing fights. Floyd vs Khan is such a BS fight and is a disservice to boxing. Khan has fast hands but obviously no chin and holds after every single exchange. Floyd throws 1 or 2 punches at a time and was holding a heck of a lot last night versus Maidana. What is Floyd's fascination with Khan? The fans DID NOT want it a few months ago and dont want it now.
