Few things, once transplanted, do as well has they had done on their original soil.
I can't think of any professional sports team that has.

But I can't think of any professional sports team that has.
Edited to clarify.
Let me help you:
Los Angeles (formerly Brooklyn) Dodgers--One WS win before 1958, five wins since.
Atlanta (formerly Boston and Milwaukee) Braves--World Series win in 1995, five WS appearances, and until 2006, 16 divisional titles since 1991.
Oakland (formerly Philadelphia and Kansas City) A's--5 WS titles before moving to Oakland, 4 more since--and 2 more WS appearances.
Even the storied and hated Yankees, they of the 26 World Series titles, were formerly the Baltimore Orioles in 1901-02.
About the only team which HASN'T had the success they enjoyed prior to their move (and this should make freedumb2003 VERY happy) would be the San Fran (formerly New York) Giants, who have been to the WS 3 times (losing to the Yankees in 1962, the A's in 1989, and the Angels in 2002). While in New York, they won 14 pennants and 5 WS titles.
St. Louis Rams--No Super Bowl titles before moving to St. Louis. Two NFL championships, one in Cleveland, one in Los Angeles (pre-Anaheim).
Baltimore Ravens--Formerly Cleveland Browns. Won Super Bowl two years after moving to Baltimore. Cleveland remains one of six NFL teams never to have played in a Super Bowl game, the others being Jacksonville, Detroit, New Orleans, Arizona, and Houston Texans.
Speaking of Baltimore--
Indianapolis Colts--Won one Super Bowl when they were in Baltimore, one in Indy.
Tennessee Titans--Formerly Houston Oilers--Appeared in Super Bowl, losing to transplanted Rams.
Decatur Staleys--Became the Chicago Bears in 1921. I think we all know how they turned out.
Boston Redskins--Became Washington Redskins in 1937. Again, a storied franchise.
National Hockey League:
I'd get into this in greater detail, but aside from the "Original Six" (Detroit Red Wings, Montreal Canadiens, Toronto Maple Leafs, New York Rangers, Boston Bruins, and Chicago Black Hawks), virtually every major franchise has moved at some point or another. A few recent Stanley Cup winners:
Carolina Hurricanes--formerly Hartford Whalers
New Jersey Devils--formerly Colorado Rockies, formerly Kansas City Scouts
Colorado Avalanche--formerly Quebec Nordiques
Dallas Stars--formerly Minnesota Northstars
So you get my point.
