This is what people are saying. Many don't agree he had full possession prior to crossing the GL and had to go to the ground all the way to have possession in our eyes based on how they have called that rule all year long.

At no point did the ball go to the ground before the defender kicked it. Moore had established possession by getting a firm grip on the ball away from his body (after the on-the-way-down bobble). Keep in mind that the defender kicked the ball out well after the conversion was made good.
In super slow motion yes...but part of possession is going all the way down and maintaining it.The bobble in real time plus the kickout is why people are disagreeing with him having possession.
The rule was he had possession in bounds then he crossed the GL, if you thought he had possession is irrelivent.The question was, explain the ruling.
If the catch was in the endzone it would have been ruled incomplete, its funny that football fans who are submersed in the game can see it any other way honestly.
Everyone is trying to state why they though it should be a catch, sorry but i was explaining the Ruling, without an opinion...
And to answer the above poster, yes the call was right and perfectly done in my opnion and by rule.
