The first change needs to be teams pay for their own stadiums instead of them being taxpayer funded from cites and states. I don’t care if it will drive tourism, use that money to take care of the purple in the city and make the city a nice place, even make it a nice place for a stadium, but make the team owners/pro leagues pay for their own damn stadium.
Harambe was just the first casualty. The root cause was the weasel in the Large Hadron Collider shortly before that event, which shifted us into the bad timeline.
