The fight showed comparisons to Hatton v KT. The hometown fighter raising his performance by that additional 10-20% than what he's showed in his career to date.

Wheather Peterson can replicate that performance again is to be seen.

My bet is that if this fight was re-matched in Vegas then Khan would win a UD by a few rounds.

In answer to the original question, then yea Hatton beat many better than Peterson. Urango, Castillo, Paulie i reckon beats Peterson, prime Tackie even, Collazo etc.

Time will tell, but if the rematch gets made, which would make sense for Peterson, get it in Vegas at the MGM grand, big payday for him, probably a bigger payday than any other fighter out there in the division, but ultimately loses the belts.
