6. Spygate
In 2007 the Patriots were a powerhouse. Three-time Super Bowl champions, they looked unstoppable. However, it wasn’t just their brilliance on the field that got them over the line. No, they weren’t shy about using some underhand tactics either. That’s where ‘Spygate’ comes along.

It emerged that the Patriots were videotaping other teams’ training without their knowledge. The NFL fined them and removed a first-round pick because of their behavior. However, things got worse for the NFL when they destroyed all the materials. Even US Senator Arlen Specter called for an investigation.
