The Seattle Seahawks have been one of the most explosive and most efficient passing offenses in football this season (congratulations if you had that one on your bingo card!).

Chasing history: The jaw-dropping numbers behind JSN’s torrid start

Wide receiver Jaxon Smith-Njigba isn’t just leading the league in receiving yards. His 819 yards are the most ever by a Seahawk through seven weeks and he’s less than 500 yards away (485 to be exact) from setting a new single-season franchise record. That’s not all; he’s also on pace to hit 1,989 yards on the season, which would be an NFL record.

Also, quarterback Sam Darnold isn’t just seventh in passing yards. His 9.1 yards per pass attempt are tied with Lamar Jackson (who hasn’t played in a month) for the most of any passer. He’s fifth in on-target throw percentage and is third in completion percentage over expected (CPOE) at 9.1%.

But for as stellar as they’ve been, this team could run into a problem in the second half of the season, warned ESPN’s Benjamin Solak.

“No quarterback in the NFL throws against heavier boxes, more players in the box and less in deep coverage, than Sam Darnold does,” Solak said Thursday on Seattle Sports’ Bump and Stacy. “However, eventually at some point, you will run into a defense that says ‘OK, we’re going to force you to run it on us for four quarters. We’re going to send lighter boxes, we’re going to put a nickel DB on the field, we’re really going to make you actually run out of these looks.’”

Klint Kubiak’s offense certainly commits to the run. The Seahawks lead the league in run play percentage and are eighth in rushing attempts per game (29).

But their efficiency there isn’t touching what they’re able to do through the air. They have the second-worst EPA per rush in the league (-0.16). For comparison, the Colts and Bills are tops here at 0.13 and 0.09. The Seahawks have been able to score in short yardage (they’re sixth in rushing touchdowns), but they need more consistent gains.

The problem certainly doesn’t seem to be with the backfield. Instead, Solak believes it starts up front – and that it could be fixed with a midseason trade.

Offensive linemen aren’t typically dealt at the NFL trade deadline (though Seattle did find success acquiring left tackle Duane Brown at the 2017 deadline), but Solak argues Seattle is a good enough team to consider improvements for a potential postseason run.

“If I were in the room right now with (general manager) John Schneider and he asked me if we should go for (an offensive lineman), I would say let’s go for one,” Solak said. “Not with the belief that it’s going to make us better in October and November, but with the belief it’s going to make us better in December and January. If we can go trade for talent from the Browns and improve that right guard spot, let’s do it.”

The talent Solak points to is Cleveland right guard Wyatt Teller, an eight-year veteran and three-time Pro Bowler. It wouldn’t cost a heavy draft haul, but it would require spending relatively soon, as the 13-year-old Teller is in the final year of his deal.

The Athletic’s Mike Jones listed Teller as one of 10 players to watch at the trade deadline and mentioned the Seahawks, Eagles and Cowboys as teams that could use him.
