Week 1 Streaming QB: Goff, Bortles or Mariota

Hey all, so 12 man ½ ppr, 6pt QB league. I held out and didn’t draft a QB, so looking at my streaming options.

Goff, Bortles and Mariota are all on the road.

I’m leaning towards Mariota @ Miami, but he doesn’t seem to have grasped the new offense yet, which concerns me starting him week 1.

Any thoughts?
