I didn't say it wasn't a penalty, but there seems to be a consensus among other posters that it was PI. It did occur to me that the official had to watch the replay, and I wondered what he was thinking while seeing Fowler get mugged while reviewing that interception. And I too was surprised they didn't challenge on the Charles run.

Every game is going to involve a handful of bad calls by the officials. At the end of the day, there are 120 other plays for either team to make up for any human error.
