Oakland Invaders

The Oakland Invaders were charter members of the United States Football League (USFL), first taking the field in 1983. With the announcement of the USFL's move to fall, the Michigan Panthers were absorbed by the Invaders for the 1985 season, as the former did not want to compete with NFL's Lions for fans starting in 1986. The influx of Panther players helped propel the Invaders to the final USFL Championship Game, where they lost to the Baltimore Stars.
