Floyd Mayweather Jr has the entire boxing world on hold as we all await his response to the contractual deadline set forth by Bob Arum. Will he agree to fight Manny Pacquiao this year, next year, or never? Many of Floyd Jr’s critics all believe that Floyd is running from Manny Pacquiao. But, there might be another powerful force out there that has Floyd Jr even more scared than an in-ring showdown with the PacMan. Let’s examine further: Should Manny Pacquiao consider fights with Shane Mosley or Juan Manuel Marquez for 2011? Floyd Mayweather Jr is ‘caught between a rock and a hard place’. He has two powerful forces breathing down his neck. In the boxing ring, Manny Pacquiao is coming at Floyd Mayweather Jr like a storm on the horizon. Outside of the ring, the IRS is waiting like a police officer at a speed trap. So, who’s Floyd Jr more scared of the ‘Taxman’ or the ‘Pacman’? Pacman Manny Pacquiao is the pound for pound best fighter in boxing. He has the speed, strength, power, and endurance to defeat anyone in his weight class including Mayweather Jr. The Floyd critics all believe that Mayweather Jr is ducking Manny and that his fear is evident in the failed negotiations between the two camps. But, could the IRS be the bigger reason that Floyd doesn’t want to fight Manny in 2010?
