Ubiquitous sensors have probably automated out many aspects of this. NFL players now have tracking beacons which must make some assessments trivial (what players were on the field?)
It's easy enough to track objects on the field (I say easy enough, it's a lot of work), but in terms of tracking game state, that's all still done by stringers.
