The Seahawks are 3-0 for just the sixth time in franchise history -- perfect in the standings despite being far from it on the field.
After a shaky first win at Carolina, they have dominated San Francisco and Jacksonville at home by a combined score of 74-20.
They are winning on the strength of a resurgent defense that ranks as the NFL's best despite not even playing its best game yet.
That's good news for the offense, which has even more room to grow -- especially up front.
The six-touchdown performance Sunday against the woeful Jaguars was a nice confidence builder, but it really was just a preseason game that counted.
The Seahawks racked up 479 yards, including nine plays of at least 20 yards, but they remain incredibly inconsistent -- largely because of the offensive line.
The unit was dominated by the Panthers' front seven in the opener, had pass-protection problems vs. the 49ers and was wildly inconsistent against the Jaguars.
Unlike the defensive line, which can send waves of players at opponents, the offensive line is one more big injury away from disaster.
The Hawks have not played with the same five starting linemen all season since 2007. Under coach Pete Carroll, they have had 10 combinations in 2010, six in 2011, five in 2012 and two in three games in 2013.
The Hawks already have lost Pro Bowl left tackle Russell Okung to a toe injury for at least half the season, and the rest of the line is banged up: right tackle Breno Giacomini has a bothersome knee, right guard J.R. Sweezy is playing through a sore back, center Max Unger suffered an arm injury Sunday that kept him out of practice Wednesday and left guard James Carpenter is still working back from knee problems.
It all has added up to a rollercoaster start for the offense, and another subtraction from the line could send it off the rails.
It explains why the Hawks added two linemen this week: Rookie Caylin Hauptmann from Cleveland's practice squad and free-agent center Jason Spitz, who started 45 games for the Packers before missing last season with a foot injury.
Quarterback Russell Wilson seemingly has taken more hits in three games this season than he did in all but a couple of games last season. He has been sacked eight times -- a pace for 43 -- after being sacked 33 times in 2012. He also has been hit 13 times and hurried to throw 23. One of those hurries resulted in an interception Sunday.
Meanwhile, the running game has been as shaky as most in the league. Other than the Philadelphia Eagles, who lead the NFL with 627 rushing yards, no team is running it very well.
Seattle's 398 yards rank eighth, but they are averaging 3.7 yards per carry, which ranks 23rd -- and that number is boosted by Russell Wilson's scrambles and Golden Tate's end arounds and lateral screens.
The Hawks ran for 156 yards on 36 attempts Sunday, but the running backs gained just 111 on 29 runs (3.8 per carry).
They were at their worst on the left side, behind McQuistan and Carpenter, where they gained just 17 yards on eight runs through three quarters. Take away Marshawn Lynch's 27-yard dash in the first half and the Hawks gained nine yards on six runs to the right side through three quarters.
The linemen have been very inconsistent, following up great blocks with blown assignments:
**McQuistan missed his first block of the game as Jason Babin burst past him on a running play. He rallied to provide good protection for most of the game, although he did let Babin hit Wilson on a touchdown pass at the end of the second quarter.
Carroll said Wednesday, “I thought Paul McQuistan made it through the first game and survived it. He played better in the second game because he had a week of preparation at tackle. He was sharper on stuff, his communication was better and he utilized his help more. … That’s a big jump though for Paul to become a starting left tackle in the league and he’s been playing guard. He has played tackle in his history, but to play up to Russell Okung’s level is a lot to ask. But he’s performed well so far.”
**On the second drive vs. Jacksonville, Carpenter got a great backside block to help Lynch get free for 27 yards. But on the next drive, Carpenter let Sen'Derrick Marks plant Wilson on a deep pass.
On second-and-goal from the 5-yard line in the first half, Carpenter got nice movement into the second level, helping Lynch get to the goal line. On the next play, Carpenter did not get a clean block and Lynch was stuffed.
**Sweezy and Giacomini had good plays and bad as well. They gave up a sack on one play but also opened a couple of good holes for Lynch. Giacomini was obviously hobbled.
**Even Unger has been inconsistent. He was flagged for two holds against San Francisco, and he seemed to miss a couple of reads against the Jaguars, resulting in pressure on Wilson.
The Seahawks used the occasion of the 45-17 blowout vs. the Jaguars to rest Unger and Giacomini and get playing time for rookies Michael Bowie and Alvin Bailey.
Carroll said he was pleased with the play of the rookies -- Bowie played 30 snaps and Bailey 16 -- and even rewatched the game to check their progress (and possibly to see whether they are capable of starting at right tackle if Giacomini cannot play).
Line coach Tom Cable was equally impressed, telling the Everett Herald that Bowie and Bailey showed "some really cool stuff. I'm really excited about their future, our future."
Carroll said his entire line is still a work in progress, and he evinced a sense of disappointment that it has not started better.
"Those guys are continuing to progress," he said. "I’m still waiting for us to really hit it in the running game. I don’t think we’ve gotten back to that level that we had the second part of last year where we were really precise and really moving it and were really being explosive. I think we’re going to continue to get better."
But first they have to get healthy.
