The Super Bowl may be TV’s biggest event of the year, but inside the stadium it doesn’t feel as large as a playoff game or even a regular season game, according to CBS’s play-by-player Jim Nantz.

At Mercedes-Benz Stadium, Nantz will call his fifth big game, though his partner, Tony Romo, is a Super Bowl rookie.

“I think for his sake, as a first timer in a Super Bowl, it is a bit stunning,” said Nantz of the in-stadium atmosphere.

That is why Nantz has told Romo about the “corporate crowd” at the Super Bowl.

“ ‘I just want to put that in your head so don’t be disappointed,’ ” Nantz said he told his partner. “‘When we call the game, it may feel like we are in a studio versus being inside a raucous, hostile environment, like we see in most places in the NFL.”

The duo broadcast a game in Atlanta on Dec. 2, allowing CBS’s top crew to get a feel for its surroundings.

“The Falcons were suffering through a disappointing season and it was very low key,” Nantz said. “It was the worst crowd we had all year. Our games are always the big game, fever pitch and all that. It wasn’t there. I didn’t know whether to chalk that up, ‘Man, this stadium doesn’t know how to hold its sound.’ You go into some of these buildings and it is pulsating. All the noise and the decibel levels are bouncing off the walls. I got no sense of presence that day in Atlanta.”

Nantz said the Super Bowl will have a fine enough atmosphere, just not as raucous as most weeks during the season in teams’ home stadiums.

“It is not, to me, going to be dull,” Nantz said. “It is not going to be what we had at Arrowhead Stadium [in the AFC Championship]. That’s just a reality.”

Pregame Chatter: Nantz says Romo’s brain is “brilliantly fast” and that on Super Sunday, they will sound like they do every week.

“I’m going to put my Romostradmus hat on and I’m going to make a prediction: Our game is going to sound just like it did for the last two years,” Nantz said. “Tony, my prediction, will be spectacular.”

Watch list: The other day when asked to name NFL players to watch, CBS sports chairman Sean McManus mentioned Benjamin Watson. Watson will be part of a roundtable during Sunday’s Super Bowl pregame. He and Greg Olsen could be the top TV free agents potentially on the market this offseason. Olsen will appear on ESPN’s “NFL Countdown.”

Double Coverage: If you watch former Pro Bowl receiver Steve Smith on NFL Network, you know he is pretty good on-air. He is a bit curmudgeonly, but very entertaining and doesn’t back down from anyone. How does he think Giants receiver Odell Beckham Jr. is doing in his career?

“What was his contract?” Smith said. “Looks like he is doing pretty damn good to me.”

Smith added that Beckham, 26, is an extraordinary talent and emphasized his youth, which is magnified in New York.

Kay-O: ESPN New York’s Michael Kay was No. 1, and Mike Francesa was No. 6, according to the Barrett Sports Media Awards. Comprised by Jason Barrett, the awards surveyed 51 program directors from around the country as to the best local afternoon talk show. In the mornings, “Boomer & Gio” was second behind Boston’s 98.5 FM’s “Toucher & Rich Show.”
