That's former Vice President of NFL officiating Mike Pereira taking a jab at Gruden's color commentating abilities. If you still can't put a face to Pereira, he's that guy that pops up on FOX many times when a play is challenged and offers his opinion about the challenged play and makes small talk with the announcers covering the game. I think he's a pretty solid addition to the telecasts as he offers another opinion on a controversial play other than the alternative of Joe Buck rambling for minutes uninterrupted without football as a distraction.
Anyways, twitter beef is one of my all-time guilty pleasures. It's especially great when it's two somewhat famous people taking potshots 140 keyboard mashes at a time for the public to see. Sadly, it does not look like Gruden has a twitter account as I have my doubts this one is him, so if he offers a retort it will not be 140 characters of rage coming back @MikePereira.
Since the internet is yet to develop a sarcasm font, I think it's fair to accept this as being the literal way he watches the telecasts on Monday night. Hopefully as he is muting Gruden and unmuting Tirico a couple hundred times a game he is not confusing Jaws with Gruden and missing out on his wonderful pearls of wisdom.
I almost wonder if the scoreboards in the stadium had the down wrong, and that's what Buck and Aikman were looking at - would explain Jones' blunder.
Buck is a flipping a**hat. He is a Detroit HATER! Whether baseball or football, he will underline mistakes and beat them to death, while blowing off our fabulous plays. Minimalizing any efforts made doesn't mean they don't happen, and people in our Great State of Michigan do not want to see or hear you "announcing" our games.
