All the blame on the replacement refs vol. Is there an agenda?

[Betonblck]

I see all these complaints about the replacement refs but the regular refs have blown just as many crucial calls. I can think of the Calvin Johnson TD where he didn't get up and hand the ball to the ref so it wasn't a TD. Normally, the commentators never criticize calls and try to act as if nearly all the calls are ok because just like the players, they aren't really allowed to criticize the officials. Does anyone think there is an agenda here?
