K.J. Wright is real.

Right now, that’s real good.

This time last year, Wright was playing for his career.

He had just signed a two-year contract before the 2019 season. But he knew the deal was really on the team’s terms, not his. Only the first year was guaranteed. He’d have to earn 2020.

He did that last season. His sparkling rebound in 2019 from knee surgery the year before was one of the better seasons of his decade in the NFL.

Yet before this season, with his salary-cap charge of $11 million for 2020 among the highest on the team, some thought the Seahawks should cut Wright.

That would have been as dumb as, oh, not drafting Russell Wilson.

Anyone who thinks he no longer has it at age 31, 10 years into his career, isn’t watching Seahawks games — or particularly their game Sunday in steamy Miami.

The longest-tenured Seahawk can still bring it.

He had eight tackles. Some of those were instantaneous on quick passes outside that he’s made a career specialty out of destroying. He had three pass breakups, one at the goal line to deny the Dolphins a would-be touchdown in the first half. He could have had two interceptions. He delivered a nasty shoulder hit to a Dolphins pass catcher that almost separated the cleats from the soles of his shoes.

Wright also forced a fumble. He again showed if there’s a screen pass, he already knows it’s coming. He’s been one of the league’s best at ruining those for a decade.

He basically roamed all over Hard Rock Stadium except the concourses from his outside-linebacker spot in Seattle’s 31-23 victory at Miami. He was perhaps the best player on the field to keep the Seahawks undefeated through four games.

I asked Wright after Sunday’s game: How happy are you that you’ve answered the challenge your team posed to you last year and remained one of the most trusted, and plain best, members of the Seahawks’ transitioning, post-Legion of Boom defense?

“That’s a good question,” Wright said after Sunday’s game, wearing a T-shirt that read “BLACK & EDUCATED.”

“I believe that when I look back at my career I’m going to be very happy. I believe in my 10th year, to look the way that I’m looking is, I’m truly thankful. I look excellent. I look great. And I’m thankful that I’m healthy, still ballin’.

“To play 10 years in this league, to play 10 years with the Seahawks and still look this good, I couldn’t ask for a better career.”

Yet the man Seattle drafted in 2011 knows better than any other Seahawk this is only the first week of October. Being 4-0 means nothing, yet.

“We got a long ways to go,” Wright said. “And I’ve got to make sure I finish strong.”

The Seahawks defense entered Sunday having allowed 1,292 yards passing, the most in NFL history through three games. Wright and Seattle weren’t perfect Sunday, either. Ryan Fitzpatrick, Miami’s 37-year-old quarterback, threw for 315 of the Dolphins’ 415 yards against the Seahawks.

But Wright noted a change in the Seahawks’ schemes Sunday. All-Pro safety Jamal Adams was out with a strained groin he got the previous week in the team’s shootout victory over Dallas. Adams has been the best and most frequent blitzer among Seattle’s back seven defenders this season. Without him, the plan for Miami by defensive coordinator Ken Norton Jr., always with coach Pete Carroll’s blessing and fingerprints, was to blitz less, cover more and drop Wright with All-Pro middle linebacker Bobby Wagner deeper into coverage than in previous games.

Carroll advised this was the defensive plan just for Miami.

Thing is, the coach hinted Friday the Seahawks may also hold Adams out of next Sunday night’s home game against Minnesota (1-3). Seattle has a bye after that game. So Adams could get from the Dallas game Sept. 27 to the Seahawks game at Arizona Oct. 25 to rest that groin for the final 11 games of the regular season, and, the team hopes, beyond.

“This was just this game and this plan and what we needed to do to in keeping them in front of us and all of that, and it worked out fine,” Carroll said. “When you have Jamal on your team, he is such an extraordinary football player that you have to use his talents.

We just adjusted a little bit today. I thought we did a nice job. I thought Ken did a really good job of putting it together so we could play a good, winning football game.”

Many of those record yards passing Seattle allowed in the first three games came on crossing routes behind shallow playing linebacker and in front of the Seahawks’ deep-dropping defensive backs. Wright and Wagner, particularly as the two linebackers in nickel defense with fifth defensive back Ugo Amadi, took away many of the intermediate pass routes the Dolphins had in their plan.

Of course they did. They study film of previous games, too.

“We knew that balls can’t get over our heads this week,” Wright said. “We know we’ve got to synch back, keep everything in front of us. And I believe we accomplished that goal (Sunday). You get what you emphasize, and the coaches really harped on that.

“We’ve got to buzz to the flats (to get to receivers outside and short). We’ve got to get back in our hook drops (over the middle)…and I think we did a good job of stopping them today. Tremendous game plan.

“Bobby told us, ‘Fellas, just execute what the coaches ask us to do and we’ll win this game.’

“And, so, we made it happen.”

Wright has been around long enough to know three-fourths of the season remains. Seattle being 4-0 will mean nothing if they don’t win the NFC West and get home playoff games in January, to avoid the road games in the division round that has ended the Seahawks’ season five consecutive tries.

“I know it’s fun,” Wright said of his team’s first 4-0 start since 2013, its only Super Bowl-championship season. “But our mission is still to win the West.

“And we haven’t played any of those guys yet.”
