There is one thing I can think of that could make a difference.
Being able to challenge penalties. By that I mean, you can throw the red flag and then challenge if something is or isn't a penalty.
Example: Throwing the flag on the interception TD to show Decker was PI'ed, or that Williams kicked Thomas as another PI.
That or force the upstairs to be able to flag plays, but then holding calls could get insanely abundant.
