Get rid of the defer option on the coin toss. Do you want the ball now, or at the start of the second half? End of choice. It's always been asinine to me to say "I won the toss, but I want to decide later what to do with it". Like 99% of the time, the winner wants the ball to start the second half, so the loser gets the ball to start the first half. There's the rare case where Belicheck wants to act smart and say we'll do something different because our stadium has a hideous gap in it that lets the wind rip right through, but he can save those shenanigans for OT coin flips.
I know it's ad revenue, but the commercials are killing televised games. Guy scores, they kick the PAT, then commercials. They come back, the kickoff goes into the end zone for a touchback, then there's a shot of the offense jogging out onto the field, but then it cuts away and we get more commercials. UGH. Everytime there's a slight stop in play because a player is down, even if he pops back up in 5 seconds because he just got the wind knocked out of him, too late we missed it because we're already in more commercials. If there's a challenge flag thrown, we launch more commercials while the refs take a look at the monitor and talk to command central and to radio up to Jerruh's booth to see what he wants. The 2:00 warning turns into the 8 minute break because I swear there's 17 commercials in that one. A game that has four 15 minute quarters should not take 3.5 hours to televise.
Stop with the mini-interviews of coaches as they head into or out of the locker room at halftime. They NEVER say anything worth hearing, no matter if they're down by 20, up by 30, or tied. "We did X well, we need to do Y better, gotta stop committing penalties and tighten up the turnovers". Yawn.
As
@rockaction just said, stop with the "Rules Analyst" being buzzed in everytime there's a flag, or a challenge. Whoever it is will ALWAYS agree with whatever the ruling on the field is, because he's not going to run down his fellow officials (ex-coworkers). Then if the call is overturned, he'll always agree with that too, because he's not going to run down the command center/Riveron/whoever is the decider. If the call is upheld, then it's basically "see I told you so". Get rid of him already. Romo and Aikman know the rules well enough to do that guys job,
and they're already doing it before they buzz in the Rules Guy anyway.
