I also think Chirrut's ability to feel the force (if not use it) might be a nudge in the doorway to allow Finn to be a relative normal guy who can, through determination/force of will, actually tap into it despite not having a natural affinity.
Jedi didn't even consider that sort of shit a possibility.
I'm stupidly hoping we get a ReyFinn v Ren lightsaber fight based on that premise.
