Sam Darnold has received a lot of compliments over the past year-plus.

He hasn’t gotten one like this.

Jets wide receivers coach Shawn Jefferson has clearly been in awe of the 22-year-old quarterback – and he won’t bother to pretend otherwise.

“Excuse my French when I say say this, but he’s a f------ dude,” Jefferson said. “He’s a f------ dude with a f------ arm and he’s accurate as s---. So excuse that."

Well, OK then.

Obviously, that’s an emphatic endorsement of Darnold’s skillset. But what exactly is it that’s wowed Jefferson so much in their few months together?

“It’s everything," Jefferson said. “The way that he works – he’s here early in the morning, he stays after, he probably doesn’t leave this building until six, seven at night. He’s in the old quarterback room. I’ve been so impressed with this kids work ethic and the way he attacks everything.

"It’s just been awesome to see a young kid like that. It’s almost like he’s been here before. He’s a young guy, but he has a lot of veteran attributes to him.”

Jefferson said that feeling has been contagious around his wide receivers. The level of trust between Darnold and his targets exists in large measure because they know he’s legit – even if he’s still a work in project at age 22.

“I haven’t been around a guy like that and it’s awesome to be around a guy like that,” Jefferson added. “He’s a dude."
