It'll happen, IMO. Too much money involved. Pacs got the date he wanted, the split, the weight and the huge penalties for going over; so I can't imainge him balking unless he's actually does juice.

Thats the trap PBF has set for him: either fight or appear to be a cheater. Maybe he needs a way to save face (I thought the dropping of the USADA stipulation would provide him cover) but other than that there really is no reason for him to avoid signing.
