Pittsburgh Steelers

The Pittsburgh Steelers have long been known for their defense. But even when you're the best at something, you have to innovate. That's why the team is now using motorized dummies at practice.

The new robots, which are called Mobile Virtual Players (MVPs), were developed by researchers at Dartmouth and featured last year, when engineers were still fine-tuning the devices.

According to Bleacher Report, the dummies have a 5.0 40-yard dash time. The dummies are controlled by remotes, and they do not fatigue, although eventually their charge runs out. Battery life seems like a safer concern than head trauma.

For the Steelers, and potentially other NFL teams, this means a constriction of risk among players, on offense and defense, during summer practices. Eventually, it will be important for everyone to get their reps in, but this can potentially keep players fresher than before.

The Steelers posted the full video on their website.
