PBF will have to live and die by the jab in this fight. He can't stop throwing it at any time because that is the ONLY way he can control Mosley. Mosley is going to try and outwork PBF so Floyd's gotta let his hands go this time around.
If Mosley's plan is to put heavy emphasis behind his jab (which isn't just lazy but ultimately ineffective), he's going to find himself in really bad shape.
