Geno Smith believes he can play even better after leading the Seattle Seahawks to a victory that lifted them to the top of the NFC West.

Unfancied and seen as a rebuilding team after the decision to trade nine-time Pro Bowl quarterback Russell Wilson to the Denver Broncos in the offseason, the Seahawks are now 4-3 after the latest success authored by Smith.

The former first-round pick of the New York Jets is penning a remarkable comeback story having beaten Drew Lock to the starting quarterback job in Seattle. 

Smith went 8-8 as a rookie with the Jets in 2013 but saw his career fall apart from there as poor play, a fractious relationship with former coach Rex Ryan and a now infamous locker room fight in 2015 derailed his hopes of being the long-term answer in New York.

He spent seasons with the New York Giants and Los Angeles Chargers before eventually landing in Seattle as Wilson's backup in 2019, playing three games in relief of the injured starter last season.

The Seahawks won only one of those starts, and there was little to suggest he could lead them to playoff contention in 2022. However, they have now won three of their last four games, with Smith leading the NFL with a completion percentage of 73.5.

Sunday saw him complete 20 of his 27 passes for 210 yards, two touchdowns and one interception as the Seahawks saw off the Chargers 37-23.

Asked by Peter King for his Football Morning in America column what surprises him most about his and Seattle's success, Smith replied: "Nothing. Nothing has surprised me. In fact, I know I can play a lot better.

"In my rookie year playing with the Jets, we went 8-8 and missed the playoffs by one game. The reality is it's hard to win the NFL with a young quarterback. That's just the reality of the NFL.

"So much goes on that you have to know in order to be successful. Quarterbacking is a skill more than just a talent. I'm just happy I've just continued to develop.

"I know I might've struggled out the gate in pro football. That's just the reality of the NFL. Sometimes they give up on you fast.

"The numbers at the beginning of my career are kind of skewed, if you ask me. If you look at Peyton Manning, if you just judge his rookie season, you'd never think Peyton Manning would've become what he became. Steve Young, too. Troy Aikman. The list goes on and on and on.

"[You have] just got to have patience with young quarterbacks. You have got to find the right young quarterbacks with the right mentality who are going to continue to work and have a great attitude about the game and the struggle.

"Over the years, not playing was heartbreaking. I’m so competitive, and I love playing so much that I really wanted to be out there every single game. But what's that cliche? 'What doesn't kill you makes you stronger'?

"I know I’m better for all those years. Coming into this year, I wasn't sure what would happen [after the trade of Wilson to Denver].

"When [Seahawks coach] Pete Carroll hit me up and was like, 'Hey I'm giving you opportunity to compete for the job,' I mean, that’s all you have to say to me. That was awesome. He's shown faith in me. That's just what I need.

"You ask me: what am I focused on during the week? Playing hard, doing what I'm coached to do. It's that simple. I don't think about failure.

"My thought process is I need to run on the field with my linemen and play just as hard as they're playing and do exactly what I'm coached to do and then let my talent take over after that. It's that simple in my mind.

"Our success so far starts with the trust and belief of our head coach. Not many coaches would start two rookies on the offensive line, a rookie running back, two rookie cornerbacks.

"Not many coaches would be comfortable starting a quarterback who hasn't played in many years. But Pete does it because he knows what he's looking at. He's played young guys before, lots of times. He's taken chances on players, lots of time. He knows how to coach ball. You can see that this year.

"I think we're built to last for this season and many seasons. But ultimately, it comes down to what we do, not what we say. It's about the work we put in. It's about the consistency. And our preparation and consistency and our togetherness. That's all that matters.

"As long as we continue to build together, the sky's the limit. It takes work. It takes hard work. We have got to embrace that part of it."
