I'm curious - at the end of the season STH picnic at the park, was there much of a line for Andre Dawson autographs? Was he even recognized? This town will never get a feel for the Expo history. It really isn't in this city's consciousness.
In terms of baseball consciousness, you have to be 50+ to really remember the Senators 2.0, and the first Nats / Senators is mostly a history book learning exercise, with some oral history from Phil Wood, Boz, Welch, Gleason, and few others.
One reason FP is going to talk about Expo history is because he was an Expo. This is like a Jerry Remy talking about playign with Nolan Ryan in California, or Jim Kaat talking about the Twins on NYY broadcasts. It is his baseball frame of reference, as is his time with Oakland and his announcing / radio career covering the Giants. What he needs to realize is L'Grande Orange is alien to most (not all) of his audience, that Rick Monday is a hero and not a villain, that Vladi is an AL player who can't run to most of his audience, and that the greatness of Rock Raines needs to be explained to anyone under 30.
