Jon Gruden is back on the sidelines, but he hasn’t lost his voice.

Now on the other side of the microphone, the Raiders’ new head coach held court Tuesday at the NFL’s annual meetings, showing off once again his penchant for being a quote machine on a wide array of topics.

Most notable was Gruden’s disdain for instant replay, an area that has only brought up more questions since it was first introduced into the game.

“I’d like to eliminate instant replay, honestly,” Gruden said. “That would be my No. 1 thing. Let the officials call the game. That’s just my opinion. I try not to play that game of ‘wish list,’ you know what I mean?”

Even though he had full access to all of the slow-motion replays up in the booth as an ESPN analyst, Gruden believes the league would be better off without them.

“I think slow-mo replay is the biggest problem with replay,” he said. “When you’re looking at ‘Is it a catch or isn’t it a catch?’ at that speed it’s hard to tell. So I think if you threw that slow-mo out, I think you’d get back to common sense. Let the naked eye determine some of these calls. But it always looks like pass interference when you’re going that slow; it always seems to look a little bit more dramatic in slow motion.”

Gruden said he doesn’t like or understand many of the new rules, harping specifically on the confusion over what is and isn’t a catch. He spoke shortly before the league announced a new catch rule aimed at eliminating some of the controversy was unanimously approved by owners.

While Gruden hasn’t been able to meet with his own players as much as free agents because of the collective bargaining agreement’s offseason rules, he does have history with some of them, including quarterback Derek Carr. The Fresno State product was on Gruden’s QB Camp show and left a memorable impression.

“He hit the bull’s-eye in the target, smashed my GoPro. That ticked me off,” Gruden recounted to a table of laughs from reporters. “Then he looked the free safety off an he smashed the other GoPro. I said, ‘That’s a wrap! That’s a wrap!’ That’s the greatest show of all time. I’m surprised we didn’t win an award for that show.”

Among Gruden’s other best hits on Tuesday?

On critics who have questioned whether he can adapt after being out of the league for 10 years: “Who are my critics? Has anyone criticized them? … You’ve got to adapt or die, and I don’t plan on dying.”

On the idea of staying on the East Coast between road games: “I want to come home. I’m like Dorothy in that movie.”

The 54-year-old also longed for the days when the college game did a better job of producing blocking tight ends and talked about wanting to bring back the work ethic and character of his first Raiders team in 1998.

While he wants to turn back the clock in some ways, Gruden told the Las Vegas Review-Journal on Monday that the Raiders are going to have more analytics than any other team.

“We have all the gimmicks and gadgets, and we’re going to have a DJ on the practice field,” he said. “We’re going to throw bubble screens and RPOs [run-pass options]. We’re going to have all the statistical data that everybody else has.”

But Gruden couldn’t leave town on Tuesday before opining on Colin Kaepernick, saying that the free-agent QB will “probably” be back on a roster soon — just probably not his.

“I think there’s a lot of intrigue there,” Gruden said.

Just as there will be the next time Gruden steps in front of a microphone.
