Dave Krieg hit Paul Skansi with a 12-yard touchdown pass, his fourth of the day, as the Seattle Seahawks scrambled from behind to beat the winless Atlanta Falcons, 30-26, today in an NFL game whose fourth quarter featured four touchdowns, a field goal and a safety.

The Seahawks (4-2) trailed by 26-21 when they started on their own 14-yard line with 5:17 to go. They went 86 yards in 16 plays, all but one in the air, for the game-winning touchdown.

Krieg, who completed 33 of 51 passes for 405 yards, found Skansi all alone in the back of the end zone.

With 20 seconds to go, Randy Edwards caused Atlanta quarterback Dave Archer to fumble on a play that started on the Falcons' 20, and the ball bounced out of the end zone for a Seattle safety.

"We battled and scraped," said Seahawks Coach Chuck Knox, "and we came back. That showed a lot of character."

Krieg also threw scoring passes of 12 yards to Steve Largent, 32 yards to Charle Young and 24 yards to Byron Walker. His pass to Walker gave Seattle a 21-9 lead.

Archer, starting ahead of 10-year veteran Steve Bartkowski, rallied the Falcons in the fourth quarter with a 12-yard touchdown pass to Billy Johnson and a 37-yard scoring pass to Anthony Allen.

Mick Luckhurst kicked his fourth field goal of the game, a 40-yarder, for Atlanta's final points.

Atlanta fell to 0-6 with its 15th defeat in 16 games.

Krieg, who passed for a club-record 32 touchdowns last season, increased his 1985 touchdown passing total to 15.
