If Mitchell keeps performing like he did against Prescott, he will earn his riches, and a shot at Khan. He was excellent that night.
You could be right but there's a saying....... "In boxing lightning often strikes twice!" Why do you think he's not been back in with prescott yet?
Some boxers are more famous than others. What a revelation. Do Kevin Mitchell and Frankie Gavin have World Titles, did they captivate the nation with their performances at a mainstream international sporting event like the Olympics? Find the answers to these questions, and then you'll have the answer to your own.
If, indeed, one can look at all "excellent" by clinching constantly and throwing a handful of punches per round against an opponent who doesn't throw so much as a jab unless you stand rooted to the spot for about a half hour. He did what he had to do - which, incidentally, is what Vazquez already did much more convincingly. That is all.
