The fact is that he blew the call and cost the Saints six points, and he did it in front a National TV audience. There is too much at stake to let that happen without correction.
As long as officials make mistakes of this magnitude protocols will rightfully be put into place to correct them. Yes it is just one regular season game but at the end of the year you look back and see one game margins in divisions, playoff seeds, etc., and that doesnt begin to cover the fact that a FR and a TD was taken off a player's resume, which could help him get further compensated.
The simple fact is there is too much invested in these games to get momentum turning plays dead wrong, especially when an easy fix (not blowing the whistle) is available.
