Did the Bengals get robbed?

[Nepa]

Bengals players on the calls within 2 minutes (from bengals.com):

"Wilson thought it was clean.

"Cooper came up to me and tried to push off of me and I thought I made a good play on the ball and the refs saw otherwise so, it's a tough call," said Wilson...

It was a tough sequence for past playoff heroes. On the next snap from the 4, the Bengals couldn't take advantage of a Rams holding call when strong safety Vonn Bell was called for what looked to be a nebulous roughing penalty against Kupp."
