Seahawks see progress after first preseason game

In critical areas like the offensive line, backup quarterback and Seattle's stable of running backs, that development was far more important than the 17-16 victory over Kansas City in the Seahawks' preseason opener.

Backup quarterback Trevone Boykin played adequately even before the final drive, when he took the Seahawks 88 yards in the closing seconds and hit Tanner McEvoy for a 37-yard touchdown on the final play of regulation.

[...] undrafted rookie defensive back Tyvis Powell showed his versatility with a couple of standout plays on special teams and an interception on defense.

Justin Britt seemed to adjust well to his move to center, tackles Bradley Sowell and Garry Gilliam played well and rookie Germain Ifedi made a few mistakes but overall held up in his first professional game.

Boykin was 12 of 22 passing before the final drive when he hit all four passes, including the touchdown to McEvoy.
