Adam Gase’s message to Sam Darnold after he became the new Jets head coach was simple and pure: Let’s get after it and have some fun.

Gase will have the enormous responsibility of developing Darnold, who had flashes of brilliance in his rookie season.

The promising quarterback is all-in with his new coach.

“I couldn’t be more excited about this, to be honest with you,” Darnold told the Daily News Thursday. “I’m really pumped about this opportunity to be with Coach Gase…. with his mind and ability to lead a team. He’s a good dude. The excitement and the passion that he has for the game is very contagious. I think that will rub off on a lot of the guys…. I’m super pumped about this whole thing and couldn’t be more stoked for the opportunity.”

Darnold and Gase spoke via phone during the hiring process before touching base after Christopher Johnson and Mike Maccagnan pegged the former Dolphins head coach to take over. Gase, who is expected to be formally introduced on Friday, has the goods to unlock Darnold’s gifts.
