Fobes.com recently released their list of the most valuable MLB franchises and -- surprise! -- the Cleveland Indians were very low on the list. The Tribe ranked 27th in the league with an estimated evaluation of $800 million, quite a ways under the median $1.3 billion worth of all 30 teams.
Forbes also estimated that the Tribe's 2015 revenue was around $220 million while the team's operation income (what they made after accounting for the cost of operating the ballpark for 81 games) was around $18 million.
The only teams with a lower value than the Indians were the Oakland Athletics ($725 million), the Miami Marlins ($675 million), and the Tampa Bay Rays ($650 million).
