There are many teams overlooked because of either their management and players on teams that cause problems or that there are really no well known all stars or that there are very few known.
The Mets are often overlooked because of their terrible Mangement and their frequently injured players wheras the rockies are overlooked because their arent a lot of well known all stars on the team.
People often look to support teams who have a lot of all stars that are well known and that have been constanlty in the running or have just been winning. For example the New York Yankees and the Phillidelphia Phillies.
But now its somone elses turn to shine somone out of the ordinary such as the Mets or Rockies.
