Pacquiao agreeing to the 14 day cut-off for the blood test is good news. He, now, is agreeing to Floyd's demand in the initial negotiation and did not ask to meet in the middle, which is 18 - 20 days.

I don't think this should be a problem for Floyd. Even if they suspect Manny to be using, Manny is still the underdog. So this implies that even a 'drugged-up' Manny is no match for Mayweather.

So what else can go wrong in this negotiation?
