Thanksgiving FLEX Decision

So with so many players playing today I find myself making my FLEX decision on a Thursday afternoon.
In a .5 PPR league would you start:
Fitz v JAX
Morris v LAC

This year has taught me to have faith in Fitz even when im worried about him but that JAX defense has me concerned. LAC on the other hand feels like a great matchup for Morris with Smith looking like he should be in at LT.

Thoughts? Comments? Concerns?
