On one hand, I see what you're saying. On the other, if any fighter were offered a fight two weight classes above where they should be, I can understand why that fighter would be reluctant.
God Damn it!!! I wish all these so called "boxing fans" around here would put enough effort into following the sport to at least read the ****ing news! The single largest road block to making Williams/Martinez II was Lou di Bella, Sergio's promoter!
Why? Look at what they both have done since the first fight. Sergio is the Undisputed MW champion. Williams is just a former WW champion.
Williams knows he got a gift in the first fight. Williams is scared Martinez is going to humiliate him again.
