I’m pretty sure what we see on TV isn’t one seemless feed. It’s the (slightly/sometimes) lagged video feed, OVERLAID with the score big graphic (which CAN be perfectly synced w the stadium clock) on top of it.
That’s where you get situations like this:
The NBC time in this photo IS the actual time on the stadium game clock in the moment. The problem is, the video that they’re associating with it is a fraction of a second slow, which is why the clock in the video feed shows 1 additional second on the clock.
This isn’t a huge issue in the scenario above, because we can see what the real in stadium clock is showing n the same frame as the action on the field. But in the Michigan case, the in stadium clock wasn’t shown on the broadcast at the time of the play, leading viewers to assume the NBC clock was perfectly synched w the video feed they were seeing, which it wasn’t.
