Every state and city wants to have good teams that compete for championships. They want to have banners raised every year. Indianapolis hasn’t had a pro team win a title since 2006 when the Colts won the Super Bowl. They might be the best hope for another one.
The Indians aren’t great as far as AAA baseball goes. The Pacers, while competitive, look to be just a middling playoff team as currently constructed. Even the Indy Eleven look like they are far away from a title. But the Colts are the team that could win that championship.
Even if you look at college teams, the Colts still have the best shot.
