Yeah, because as an event, it will be decent. I don't think he comes close to winning, but he could pose problems for Mayweather in some way or another. I don't see anybody else making a Mayweather fight competitive anyway. Thurman is probably the most dangerous, but he hasn't really had the exposure to generate massive money in a Mayweather fight. After that, he's beaten Cotto, Alvarez, Pacquiao, Marquez and Maidana, who are all the closest ranked fighters to him in both of his ruling divisions.

So that leaves...

Thurman
Brook
Bradley
Porter
Broner
Khan
Andrade
Lara

So you can eliminate Lara and Andrade from the picture. They're in the 'who needs them' club. Broner is his buddy so he's gone. Porter needs a strong win. So does Bradley. Thurman and Brook probably need another 12 months of exposure. He's already beaten Cotto, Canelo (who look like they will fight eachother anyway) Marquez, Pacquiao and Maidana. Khan is the most logical option for him. He's probably the most vulnerable opponent as well as being one of the most lucrative.

He's been around long enough. His win over Alexander was exceptional. He wasn't great against Algieri, but perhaps we under-rated him based on what Pacquiao did to him. He did beat the Provodnikov who is decent enough (ask Bradley).

So based on that, i'd say he's as deserving as anyone really.
