After watching the video several times, I don’t see a way in the world Lewis could have caught the ball. Robey-Coleman had him completely blocked from catching it.
It looks like the interference was intentional, in order to stop the receiver from scoring. Robey-Coleman never so much as tried to look for the ball. I bet he was even shocked that he wasn’t called for interference.
At full speed when it happened I agree. The replays are from another angle. I thought the ball was thrown wide of the receiver.
Then it was holding and still helmet to helmet. Both enough to give the Saints the first down.
