One would think that, if you’re wealthy enough to own a professional sports team, you’ve got a good head on your shoulders and at least some sense of tact. After all, how could one be successful in business if he or she doesn’t know how to talk to people or run an organization? Obviously, sports owners must be the best and brightest of the world’s business people.

Just like in the rest of life, the ownership ranks of the NBA, NFL, NHL, Major League Baseball, and professional soccer, are loaded with complete sociopaths.

However, others like Marge Schott and Donald Sterling are simply crazy people who should not be in charge of a grocery list, let alone multi-million dollar organizations.

While many of these unstable owners ultimately end up running their teams into the ground and being forced out, some manage to stay in power for terrifyingly long periods of time. Whether through carefully-planned actions, their complete incompetence, or a combination of the two, here’s a list of the 25 Craziest Owners in Sports History.
