Other Packers playing for Amsterdam included wide receivers Chad Lucas and Vince Butler, tight end Tory Humphrey and safety Atari Bigby. Lucas, named to the all-NFL Europe first team earlier in the week, was held to one catch for 22 yards. Bigby had four tackles and one forced fumble.
Amsterdam led 7-2 at halftime, the lowest scoring half in the history of NFL Europe's title game, but Frankfurt exploded by scoring 10 points in the third and fourth quarters.
Frankfurt had a league-record 1,750 yards rushing in the 10-game regular season and gained 269 Saturday. Roger Robinson, who also had an NFL Europe record with 1,087 yards, picked up 96 on 19 carries.
"Without a question we are a running team and we did what we do best," Galaxy coach Mike Jones said.
One fourth quarter drive lasted 8:42, with the ball given to Wallace or fellow running back Roger Robinson nearly every time. It ended with David Kimball's 37-yard field goal, putting Frankfurt ahead 15-7.
Admirals guard Michael King was taken off the field in an ambulance late in the fourth quarter, delaying the game for several minutes. The injury wasn't serious.
The Galaxy, playing in a record seventh World Bowl, denied Amsterdam the chance to become the second team to win back-to-back titles. Jones and offensive coordinator Whitey Jordan became the first to win the game three times.
