The Google Play store says NFL Mobile is not compatible with my device, a Google Pixel. This is not a tablet, it's a Google phone, why is it not compatitble?
Probably because the developer didn't mark the Pixel phones as compatible. It might because there isn't a way to differentiate between the phones on the Verizon Wireless network and those on a different carrier.
We got our Pixel phones in November, and enjoyed NFL games on them all season long - the app definitely works on the Pixel for us. Did you buy the phone from Google or Verizon? We bought ours from a corporate Verizon store.
