Five Dream Teams that failed spectacularly

— -- Cleveland Cavaliers forward  LeBron James said  he wants to play alongside Carmelo Anthony, Chris Paul and Dwyane Wade before their careers end.

It's a tantalizing prospect for basketball observers -- and likely a frightening scenario for players who aren't able to join forces with them. Still, a monumental collection of talent doesn't guarantee ultimate success. History tells us that lofty expectations, injuries and downright dysfunction can torpedo great teams.

So maybe LeBron should be careful of what he wishes for as we revisit five Dream Teams that failed to realize their championship aspirations:

2012-13 Los Angeles Lakers

2011 Philadelphia Eagles

2004 New York Yankees

2003-04 Los Angeles Lakers

1980 U.S.S.R. Olympic ice hockey team
