What are the top 3 biggest fights to be made in boxing?

Of course. How many boxers right now do you think wouldn't entertain that fight? I don't mean tomato cans or guys who would are so desperate they would accept almost any conditions Mayweather's team would present. Take every promising prospect who is undefeated, every guy in their prime or veterans who are financially secure. Who do you think turns it down without even looking at a contract?
