Learning from past mistakes is one of the greatest measurements of growth.

Every Jets fan surely went into Thursday night’s NFL draft first round, in which the Jets had the fourth and 10th overall picks, hoping to see signs of growth with the team’s actions.

That growth in this draft needed to include the acquisition of offensive help to build around Zach Wilson, the franchise quarterback the Jets chose with the second overall pick in last year’s draft.

That didn’t necessarily mean both of those first-round picks needed to be on the offensive side of the ball, but at least one of them had to be used to help Wilson — specifically one of the top receivers on the board.

That could have meant using that 10th pick to trade for disgruntled 49ers receiver Deebo Samuel or drafting Ohio State’s Garrett Wilson, USC’s Drake London or taking a chance on Alabama’s Jameson Williams, perhaps the most dynamic talent of the receiver class who’s recovering from ACL knee surgery.

Yes, the Jets are in dire need of help on defense, particularly at edge rusher and cornerback. And those positions can be — and surely will be — addressed. But so, too, should skill position on offense to help Wilson develop into the quarterback he was drafted to be.

Four years ago, with a different regime of general manager and head coach making the decisions, the Jets drafted quarterback Sam Darnold with the third overall pick. And from there, they inexplicably proceeded to forget about building around him. It was as if the Jets assumed Darnold could do it himself. He, of course, couldn’t. Few, if any, quarterbacks can.

Before the Jets traded Darnold away last April, they made 20 draft picks after Darnold was drafted and 10 of those were defensive players. Only one was a receiver, Denzel Mims, who was drafted in 2020, Darnold’s third and final season in green. Mims played in only nine games in 2020, caught 23 passes and didn’t score a touchdown.

Two tight ends were drafted in Darnold’s three seasons, Chris Herndon and Trevon Wesco, almost exclusively a blocker. Two running backs were drafted, Trenton Cannon in the seventh round in 2018 and La’Mical Perine in the fourth round in 2020.

That’s not exactly building around your franchise quarterback.

Giants co-owner John Mara showed raw and refreshing honesty earlier this offseason when he said this about Giants quarterback Daniel Jones: “We’ve done everything possible to screw this kid up.’’

No one from the Jets has been as honest as Mara was in his assessment of Jones and copped to doing that with Darnold, but that’s exactly what they did.

It’s a mistake the Jets cannot afford to make with Wilson, who at times in 2021 looked every bit of the 21-year-old rookie with limited college football experience he was.

“I think when you break it down to keeping the main things the main things, it’s going to be about developing and helping our young quarterback,’’ Jets general manager Joe Douglas said last week in his pre-draft press conference.

Douglas’ offseason additions of tight ends C.J. Uzomah (49 receptions for 493 yards and five TDs last season for Cincinnati) and Tyler Conklin (61-593, 3 TDs last season for Minnesota) were a strong start as a precursor to this draft.

“I’m extremely excited about the plan,’’ Wilson said Wednesday. “I feel like the organization as a whole … everybody is very tied together as far as being on the same page with everything. I know my trust with the ownership and Joe D as well and what they’re doing, I feel like they have a really good plan. I’m excited for what they’re going to bring in for us.’’

Asked to be more specific about that plan Douglas and head coach Robert Saleh have, Wilson said, “It’s within the detail … them finding out what we need, them saying, ‘Hey, how can we grow? What do we need this year, what do we need down the road? How can we just build those pieces, lay a brick at a time?’

“Those guys do a good job of really being able to put it all into place. Now, going onto Year 2 … I feel like they are right on schedule of kind of putting everything together like we need to.’’

From Wilson’s lips to the ears of every hopeful Jets fan.
