On Sunday, the Oakland Raiders made the worst-kept secret in the NFL official by announcing the hiring of Jon Gruden as their next head coach. He’ll be introduced by the team on Tuesday, making his long-awaited return to coaching after spending some time in the broadcast booth.

Although he hasn’t coached since 2008, his return is viewed as one that should help the Raiders’ struggling offense. The Rams will get a first-hand look at Gruden in 2018 when they travel to Oakland to face the Raiders next season.

Sean McVay is already familiar with the man they call “Chucky,” having worked under him in Tampa Bay in 2008. That was nearly 10 years ago, which makes McVay wonder if Gruden will deploy the same offensive system he had then, or if he’ll change it up.

“Great coach, great motivator, great leader, great teacher in terms of just understanding the big picture,” McVay said during his press conference Sunday. “He’s gotten exposed to a lot of different things. I’ll be interested to see, will he run the same offense that he was running when I got a chance to work with him in Tampa or will he now implement some of the different things that he’s had a chance to kind of continue to get exposure to over the last handful of years?”

Gruden was known for his offensive prowess during his coaching days, and he’ll have one of McVay’s top guys in his pocket next season, as well. Rams quarterbacks coach Greg Olson is expected to be Gruden’s offensive coordinator, so perhaps the Raiders’ offense will resemble L.A.’s a bit.

“Either way, hate the fact that we’ll have to go against his next year,” McVay said. “It will be fun, but he’s a great coach and you see why Oakland is so excited about being able to get him back to the Raiders.”

McVay was asked if Gruden will steal some of his plays after transitioning from analyst to coach. Needless to say, he isn’t worried about that, and wasn’t afraid to admit he’s stolen some of Gruden’s plays.

“No. We’ve stolen his plays, so that’s more what it is,” McVay said.
