Teams are for broadcast partner pairings. If there's none close enough to the Olathe area, you may not be presented with any teams to join.
In Omaha for example, only WOWT 6 (NBC affiliate) is available for me to join.
It's not a sports team focus.
There was a way to show team support a year ago if I recall right when Waze was partnered with the NBA during The NBA Playoffs, but that was only a limited time feature.
