Small-market teams are, by nature, always at a disadvantage when competed against big spenders like the Dodgers or Yankees. It takes a sound strategy to overtake these rich juggernauts who can seemingly roll out division title after division title as if there were no other teams in the division. Recently, the popular strategy for these smaller teams seems to be to tear it all down liberally and hope to win in four or five years. The strategy worked for the Astros and Cubs, but teams just starting the process are going to struggle. Now that half the teams in the league are rebuilding, competition in the future will be heightened. Instead of being the only rebuild, you now must be the best of ten rebuilds to succeed. It is difficult to gain an advantage while mining in the same mine of your neighbor. Small-market teams need to find underdeveloped niches to succeed, but the rebuild (or tank, for those who wish to not use the euphemism) is too exposed to work for long. But there is another market niche that small-market fans, especially Diamondback fans, always talk about: the extension.
