It's close. 2006 coming off World Series hype but 2003 star power gives the edge to me. You had Frank Thomas, Paul Konerko, Magglio Ordonez, Carlos Lee, Carl Everett, Robbie Alomar, Mark Buehrle, Bartolo Colon, and Esteban Loaiza who started the all star game. Then on top of that you had Joe Crede, Jose Valentin, Sandy Alomar, John Garland and Aaron Rowand and two of the best relievers in the game in Flash Gordon and Damaso Marte. Absolutely loaded roster with big names top to bottom... aside from never acquiring a 5th starter and Konerko sucking...and they win somehow only win 85 games.
