No, they're not. On merit it was an intentional trip and a serious penalty. It was blatantly missed.
The spirit of the game on the intentional grounding, it sucked and the refs clearly watch more sissy sports like soccer than football so I understand why they didn't do what was right.
However. The Bengals first drive I saw OL pushing our defenders down hands on their back. I've seen missed penalties on both teams but not the egregious calls missed against the Bengals.
