It's both. Ralph represents 'small market' and Buffalo has become that 'small market.'
Think of Snyder, Jones, Kraft, et al. as people who want the NFL to be in the biggest markets. Just as teams moved from Pottsville, Racine, and Kenosha --- they want the Bills out of Buffalo, and they have leverage that can make it happen after Ralph is gone. It is pure Adam Smith and the 'invisible hand.'
