Pats will not play the Saints in 2019.
They will play the Eagles and Cowboys. And the Chiefs.
I still have questions about the ref's call that saved the Rams. If that foul was intentional to stop the Pats from scoring, it seems the result should've been over turned. I don't trust any institution. I'd be shocked but not disbelieving if that game was handed to the Rams to maximize SuperBowl viewership.
