The right hand for Shane is just icing on the cake, the punches he HAS to land are #1 The Jab #2 The left hook. Floyd has trouble vs the jab, hell everyone has trouble vs a good jab, and if Shane can land ANY left hooks he'll do big damage.

Shane is also going to need to catch Floyd when PBF finally tries to throw anything back which is also why the jab is important as it should get Floyd to try and counter once he gets tagged with it enough.
