My view of payroll as an indicator of Market size is that it is very unreliable. Miami is spending a lot on payroll for the upcoming season and in past seasons they have also spent big --1997 and 2002. However, they were unable to maintain those payrolls consistently because their market wouldn't sustain it. They were trying to stimulate interest and build a fan base by building powerhouse teams that won championships. It didn't work. The Nationals are trying very much the same thing. It should work better than it did for the Marlins, but will it work well enough to support a big payroll consistently? Will it work well enough to build a loyal consistent fanbase, when it has been pointed out by other posters that DC residents don't go to games and the suburban base of fans would rather avoid the torturous traffic patterns in the area? Only time will tell, as E1 would say. However, at this point in time, they are not a big market team, and there isn't a single reliable report saying otherwise.
