You don't need to be in the NFL to win a pro football championship. Teams from across the US have lifted trophies in various leagues, but the chances are they don't exist any more. Be it a failing league, or an unprofitable franchise, external factors have caused even high achieving teams to circle the toilet.
And no, the XFL's LA Xtreme are not in the list. And yes, the XFL was that bad.
#6 Sacramento Surge
Awful logo, awful name, decent team. In 1992 at least. The team played in the original incarnation of the
WLAF, playing in a different stadium (both tiny) each year, and stumbled to a 3-7 record in the opening season. As the London Monarchs went from good to bad in year two, the Surge went the other way, posting an 8-2 record ahead of a play-off win against Barcelona and beating Orlando in Montreal to claim
World Bowl II (oh, it was all so cosmopolitan).
The fact that the team's star player in 1992 was journeyman QB Dave Archer (best known for a three-year stint at the
Atlanta Falcons), may say everything that needs to be said about the quality of the WLAF. The most famous member of the team turned out to be former
Georgia Bulldogs DT
Bill Goldberg – he went on to be a wrestler of some repute.
When the league folded, the Surge kinda became the Sacramento Gold Miners in the
CFL, when the team's owner was awarded a franchise in the CFL's ill-advised American '90s expansion, becoming the first Yank team to ever play in the Canadian set-up. Archer stayed in Sac-town but during the Gold Miners' two-year stay in the CFL, the team was simply not very good.
Quelle surprise, as they say in some bits of Canada.
