Matt Hasselbeck makes a huge difference for the Seahawks, particularly against a bad pass defense.
And the Jaguars have a bad, bad pass defense (allowing 71.9 percent completions heading into Week 5).
This victory was critical for the Seahawks because it gave them a chance to reach .500 heading into their bye following a Week 6 home game against the Cardinals.
Having Hasselbeck come back so successfully also provides a significant psychological boost for Seattle, particularly with the previously upstart 49ers getting blown out at home. Seattle was dragging after three consecutive defeats. The Colts humiliated them and the future appeared bleak with Seneca Wallace at quarterback. As a backup, Wallace wasn't able to overcome shortcomings elsewhere on the roster.
Hasselbeck proved he could overcome those shortcomings against this defense -- even with Kyle Williams, signed Saturday from the practice squad, playing left tackle.
These were the Jaguars, not the Colts, but the Seahawks had too many problems of their own to worry about what was ailing Jacksonville. They needed a victory -- any victory -- and they got one.
This performance should be cathartic for the Seahawks. Their offense dominated. Their defense dominated. Even rookie Nick Reed, the preseason hero, scored a touchdown (79-yard fumble return).
Hasselbeck played as though he hadn't suffered a broken rib during a Week 2 game at San Francisco. A victory over the Cardinals in Week 6 doesn't seem so unlikely at this point.
