Miranda is on HBO and earns good money - you can call Miranda a lot of things - but he isn't stupid. He is getting the maxium amount of money from a decent level of skills. Miranda might take a belt some day and hold it for a few defenses - but he isn't going to reign - Bute might. A fight with Kessler will hopefully earn him a decent pay - and a defeat wouldn't set him back much - he'll still be known - still be on HBO and still be some-one opponents wants to face.
I agree. Miranda is lucky to have the backing he does and he deserves some of that backing by stepping up to the plate and doing his best.
Truth is, Miranda is by far the highest paid fighter I know to never of had won a belt. His team is obviously doing something right, at least business wise for Edison.
