Paul Lukas has a remarkably detailed article on ESPN Page 2 documenting the minutest of uniform changes for 2005, truly remarkable stuff.
Whether it's the old Baltimore Orioles-inspired "O's" on the present-day Orioles alternate caps:
The Braves heinous homage to the mid-Seventies Cleveland unis:
Brian Schneider's habadasherial evolution, or the color of the Dodgers road uniform buttons, Lukas has it all.
He also reviews the Washington Nationals new uniforms preferring the ones that his readers concocted to the genuine article. I have to say that I'm might partial to this one that features a map of the District of Columbia within a baseball diamond.
Lukas also points out that the Nationals home uniform has a sleeve patch that disingenuously proclaims that the team was "Established 1905". The only reference to 1905 that I can find in DC baseball history is that it was the year that the official, but rarely if ever even mentioned, name of "Nationals" was given to the Washington team. Of course, they were always known as the Senators and this date has the most tenuous of connections to the new Nationals. But then again, this is the sport that re-dubbed Estadia Hiram Bithorn the anglicized Hiram Bithorn Stadium.
