18. Dubious History
Make no mistake, baseball has one of the shadiest histories in all of U.S. sports. First of all, there were gambling scandals with the likes of the Chicago Black Sox. That’s also why Pete Rose will never make the Hall of Fame. Then along came the Steroid Era and the BALCO Report.
After this, the sport entered the sign-stealing era. In recent years, there was opioid abuse and other problems. Meanwhile, the number of lockouts and player/owner feuds continues to rise. MLB created a giant mess for itself and continues to make problems for itself (via The Athletic).
