Can someone explain the reasoning behind the game ending with 1 second left on the slow motion replay clock.

You know what an incomplete pass is right? Why would the clock run on an incomplete pass.

Anyway, the rules state there has to be 2 seconds on the clock, but what I don’t get is there is always an untimed down if there is a penalty with zeroes on the clock even if the penalty is after the clock hits all zeroes. I'm happy we got the win, but I felt after they replayed the down and 1 second was still left, I felt the Falcons had another chance. I am happy with it being in our favor, but at the same time, I'm not happy.
Nope, never seen an incomplete pass. simple error
However, an untimed play, after 0:00 is only on a defensive penalty.
