There were two questionable calls vs the Vikes, both of which ended up going the Rams way.
On one, the Vikings receiver made a tough catch and fell down, then got up untouched and continued running. To me and on replay, it looked like he was totally untouched, but the refs blew the play dead so a likely touchdown was missed by the Vikings. I don't remember if they went on to score on that drive.
Later, on a long TD pass by the Rams, a flag was thrown for block in the back, then picked up after discussion. Now there may be rules of which I am unaware, but the Ram linemen did push the Vikings defender directly between the numbers on his back.
Is this what being the popular team, and getting calls going your way a majority of the time, feels like? It is weird.
OTOH, I'm sure all of us could point to a dozen glaring offensive holdings that were totally ignored by the refs.
