In watching the Laundry catch again, the ref was not in position to see Landry get touched as he was going to the ground. He did see Laundry step out at the 40 and waved his hands to stop the clock. He was pushed back inadvertently by the Atlanta defender who initially fell behind Landry. When Landry ran the ball back to an official to have them spot the ball the other ref and refs acted as if the clock was still running. That is where I have the problem. The refs should have said Stop and take their normal time to spot a ball.
You can see the ref in the bottom right of the picture with his arms up in a waving formation. Had he rule correctly that Landry was down by contact, then all actions afterward would have been correct. Here is where a blown call that normally would have worked for the Saints where they then huddle up and call their next play, I am sure the replay dude would've stopped the game, after reviewing the catch Ask Atlanta do they want to use a time out or run 10 seconds off the clock. Atlanta would have taken the time out. Which would have left them none on their last play before the FG attempt.
Anyway the end result is a Saints win. Let's move on
