I hope they change the team's name. I hate it when teams keep their old names, even when it is nonsensical. To wit: Utah Jazz (from New Orleans), LA Lakers(from Minnesota), Arizona Cardinals (there aren't any cardinals in the desert), etc., etc.
Call them the Washington money-grubbing whores.
How that for a nickname?
That is about the best guarantee that will happen.
For gods sake, they aren't even named after anything, they are named after a one time event in montreal.
I don't even think 90% of baseball fans even know that.
My guess, something corny, like the senators (from the "old days gone by").
