MLB has had many great teams throughout its storied history, with each individual franchise finding some level of success along the way.
The first thing I had to do was find the best team in each individual franchise's history—which was a daunting task, to say the least.
I did not judge solely on winning a World Series or having the best record. When you have a 162-game season and the World Series boils down to seven games, obviously the best team doesn't always win. Just ask the Florida Marlins.
After determining the greatest teams in each respective franchise, I tried my best to rank them against one another. Another tough task, but I think the results turned out pretty well.
