The quickest way for the Jets to come down off cloud nine is to turn on the tape and watch Marcus Mariota play quarterback.

Many experts thought the Titans rookie — who visits MetLife on Sunday — would struggle making the transition to a pro-style system, and they thought wrong.

Dream kid, dream franchise quarterback.

“The biggest thing is you want to contain him, make him be a pocket passer, he can be deadly getting outside the pocket making plays,” Jets linebacker Trevor Reilly said. “The guy can make plays with his feet, not only running the ball, but when he’s outside the pocket, he can extend plays and hit receivers down the field.”

When he was a senior at Utah two years ago, Reilly played against Mariota, who was then a sophomore at Oregon. He never thought Mariota would be a project.

“I thought he was a special kind of player,” Reilly said. “Obviously they run a different kind of system at Oregon, but he’s got a good arm and he’s smart and he takes coaching well, so I didn’t see it as that big of a learning curve for him as other rookies for that position.”

Reilly sacked Mariota in Utah’s 44-21 loss to Oregon that day. The Utes stopped Mariota, limited by a knee injury, from running (four carries for negative-18 yards). But Mariota threw for 288 yards and three TDs.

“He ended up killing us inside the pocket,” Reilly said. “He made some deep throws, and blew some coverages, but we were doing pretty well against him in the first half. They took over the game in the second half.”

Mariota ran for 2,237 yards and 29 TDs in three years at Oregon. Mariota has rushed for 249 yards and two TDs this season, with 20 of his 31 carries having come in the Titans’ last four games.

“He’s gotten better every game,” Jets cornerback Buster Skrine said. “He’s a guy you have to watch out for. You play certain coverages, he might take off and run because he’s a fast quarterback. He’s playing more advanced than a rookie.”

The Jets would have been better served confronting Mariota — who has thrown for 19 TDs and nine INTs in 10 games — earlier in the season.

“I feel like I’ve gotten better every single week,” Mariota said in a conference call.

Skrine had asked former Browns teammate T.J. Ward about Mariota during the Heisman Trophy race. Ward, now a safety with the Broncos, played at Oregon before Mariota.

“They say he’s one of those guys who takes coaching very well,” Skrine said. “He’s all-in. He’s gonna come in and just be the best he can be every day.”

Mariota’s biggest challenge adapting to the NFL game?

“Just being under center,” he said. “The game’s a lot tighter, in terms of just everyone’s kinda close up on the line of scrimmage, a lot of run-heavy sets … different things I wasn’t really accustomed to at Oregon,” he said. “But the coaches have done a great job of helping me through this process, of helping me understand things, and I’ve felt comfortable throughout.”

Mariota revealed himself as the Titans’ best running threat by virtue of an 87-yard touchdown gallop against the Jaguars. The key?

“Make him try to beat us with his arm,” Sheldon Richardson said.

Mariota likes to beat teams with his arm by throwing to tight end Delanie Walker. And towering rookie wide receiver Dorial Green-Beckham is starting to emerge.

It would help Mariota, of course, if Darrelle Revis (concussion) is held out for one more week.

For all of Mariota’s rookie success, the Titans are 3-9 this season.

“It does get frustrating at times, it is tough, but it’s a part of it,” Mariota said. “You got to take it, handle adversity as it comes, and understand that it’s gonna make this entire team better moving forward, and no matter what, you just kind of stick to the grind and don’t get flustered or don’t get down on yourself for what’s going on, and just understand it’s a process and do your best to get better each and every single week.”

He is a gym rat who understands the responsibilities of a franchise quarterback. He is the anti-Johnny Manziel.

“I don’t think of it as really a job,” Mariota said.

The real job is not overlooking him.
