Sam Darnold really learned from his rookie mistakes.
And we’re not talking about the second-year Jet quarterback’s interceptions and fumbles.
In 2018, as a first-round rookie, the QB bought his offensive linemen Christmas gifts, as is the longstanding tradition in the NFL.
But his protectors weren’t exactly bowled over by their $30-million signal-caller’s choice of barbecue utensils and a $300 gift certificate for steaks.
They showed their “gratitude” by promptly jacking up his Toyota SUV and stealing its front tires.
The holiday humilation was caught on video by teammate Jamal Adams.
“Damn, Sam. Damn, Sam I Am! They got your ass, rook!” Adams says, laughing, in the Instagram video that went viral.
The USC product learned his lesson well. This past year he took his linemen out to dinner — and gave them each an electric bike.
“I imagine really big, strong bikes,” quipped a tipster, referencing the 300-pound recipients.
Jets players were mum on Santa Sam after the 2018 Christmas kerfuffle.
Other QB gifts ran the gamut in 2019.
Now-retired Giants quarterback Eli Manning played only four games last season, but the legend thanked his guys with Yeti Hopper M30 coolers, which retail for about $299.
Baltimore Ravens quarterback Lamar Jackson, the odds-on favorite to win the MVP, handed out Rolex watches on Christmas Eve. No word on whether he had buyer’s remorse after getting knocked out of the playoffs by the Tennessee Titans two weeks later.
Jets legend Joe Namath told The Post that back in the day, “it didn’t go beyond dinner and drinks.”
“You treat your guys right, they treat you right,” he said. “Times have changed. I don’t know that anyone should come to expect gifts. That’s where I come from.”
Asked what he would have done if his linemen stole his front tires, Broadway Joe quipped, “What quarterback in the league is going to mess with his offensive line?”
