The replay showed it was an obvious incompletion - what makes McCarthy's non-challenge even worse was somebody was dinged up on that play so they had even more time than normal to look at replays before throwing the red flag on the field. IIRC, it took a while before they found a camera angle that showed that the ball came loose - not until after the next play. The replays that they showed on TV initially were blocked by players on the sideline (great camera work, almost as bad as the New England game). I don't know that McCarthy had that angle - I think he had to guess and had no solid evidence that it came loose. If someone still has the game on their DVR (I deleted it right away), it would be nice to confirm/deny that. I just checked because that was my memory as well. They showed a replay that showed it hitting the ground twice before the next play, but they were either full speed or barely slowed down and not zoomed in. What effected my memory I think is that neither buck nor mailman saw anything either and were basically saying I don't see anything wrong with any of those replays so it shouldn't be overturned. They brought in Pereira and he flat out said that's not a catch but it was right before the snap. It want till 2 plays later that we got the super slow zoomed in look of it hitting the ground. I don't know what the teams get to look at to decide, but frankly there was probably enough from the broadcast to call for a review and if they are able to go through different views at slow speeds on their own then there is no excuse for that not being reviewed and probably comes down to either McCarthy not trusting whoever or being too chicken.
