Clearly Mayweather is a big favourite and a great boxer. Is there an outside chance that Floyd 's 2 year absence will leave him a bit rusty and have a bad night at the office, poor timing etc. Marquez will he have a lot more venom in his punches and outpoint Floyd?? How will Floyd cope with Marquez brilliant 3 and 4 punch combos? Floyd does have off-nights, he is human, eg. De la hoya and Castillo 1. I wonder if it is worth throwing a score on Marquez just for the interest...?? Marquez to win 5/1.
You do have a valid point their, but im not going to risk it. Mayweather win's in every single category. Weight, reach, height, age, speed, power. Everything. He's been sparring many championship rounds, I dont beleive the ring rust will be that much of a big deal to a guy like him. Anything's possible in boxing, and its a great investment if you win on odd's like that, but their's very, very little chance of success. All the best!
