I think Jon will have advantage like some LWs moving up to WWs having advantage. (stamina and speed) and overall IQ and experience in the cage.
Masvidal was just a good LW fighter but he became a great WW fighter.
As much as I want to see Jon take a devastating loss, I think Jon can win, stay outside and pick Francis apart.
Francis has more power for sure but doesn't have the speed of the lighter weights JOn faced, and even from a speedier lighter weight fighters, Jon got hit with powerful clean shots a very few times.
