 == RE: Comerica smaller size == 

 Your assessment of the ""artificial demand"" is partially true. Writers have also commented on the move to smaller parks as being due to changing demographics. To be more blunt about it, baseball is not as ""important"" as it once was, compared with certain other sports. When the NFL started, they rented from the baseball teams. By the 1960s, the baseball teams were sharing with the NFL in facilities that were decidedly more conducive to football. Now they are going their separate ways, the NFL stadiums being larger, and the MLB parks being smaller. The ""artificial demand"" strategy seems to work, as long as the product is attractive. I wonder how small they would have to make Milwaukee's Miller Park so that demand would exceed supply?"
