In the very cool ESPN Sports Science video above, Patriots rookie cornerback Devin McCourty visits the Sports Science lab for a measurement of his reaction times and speed skills. Here are a sampling of the findings:
* Over the course of 20 yards, McCourty reaches a top speed of 19.6 miles per hour.
* McCourty runs backwards 80 percent as fast as he runs forward.
