I don't understand why there isn't an official upstairs making the call immediately down to the field on all reviews, instead of the archaic looking into the hood by the head field ref. They do it for TDs, might as well do it for all replays. It would save a ton of time, although, the NFL would lose ad revenue. It's beyond sad that we as fans know the correct call almost immediately. Hell, Fox even has time to coordinate a correspondence with Mike Pereira in LA discussing the correct call well before the refs are done under the hood. Ridiculous. If we were able to make improvements to how quickly we go through the challenge process, we could add more challengeable items, like personal fouls.
