Good question. I think this question sheds more light on the upcoming contest than any stats or anecdotes.
Conor has tremendous belief in himself and has no fear or superstitions. In fact, he fought with that jacked thumb during the Poirier bout and beat Holloway with a torn ACL.
Everyone think Jose Aldo is such a hard man but he has never been the nail, only the hammer. Jose pulls out of fight after fight with injuries ranging small to severe. Add to this, Jose is incredibly superstitious and would not even go in the ring to meet Conor for promotional purposes do to some superstition he had.
Conor can adapt and overcome when things change, aren't exactly where they were expected to be or anticipated. Jose, on the other hand, needs things to be just in the right place. This type of brain is comparatively weak and stops functioning at maximum effort when things go wrong or fall out of place.
