User: Can you tell me about the history of sports in Philadelphia?
Assistant: Philadelphia host teams in the 4 major sport leagues. Over the years, there has been varying success from the teams. In some years, there have been teams at the bottom of the league. Most years, teams are within reach of the league championship. Philadelphia Phillies and Philadelphia Eagles have been teams with the most success with both teams ending as runner up to the league championship. The Philadelphia Sixers has been a top tier team but has not been able to get past the second round of playoffs in the last few years. Philadelphia sports fans are notoriously loyal, demanding of their players and aggressive against fans of opposing team fans.
