They need to get rid of automatic replay on scoring downs.
Let the HCs use their red flags if they don't think the other team scored, or believe their team did.

Not only that, but we now hear that on some plays the rule is to let certain plays play out and let replay decide. I don't like that. The on field officials need to call every play. Will mistakes be made? Yes. But the game is being taken over by replay and is changing outcomes and slowing down the game miserably.

Too much of a good thing.
