Unless they get another franchise it's already a done deal.
The Nationals
are the Expos. A uniform and name change won't eliminate decades of history.
The team has a choice between embracing its past, or ignoring it because it happened to be in another city. Currently it is choosing the former. I've never been to Montreal, and I don't speak a word of French, but I think the Expos were a cool team who wore cool uniforms, and I hope to see the team embrace that part of its past in the future.
